Site Overview: What USD Euro 360 Is, Where Our Data Comes From, and Why Nothing Here Is Investment Advice

1. The purpose of USD Euro 360

USD Euro 360 exists to answer one deceptively simple question for ordinary readers: what is something worth right now, expressed in United States dollars and in euros, and how has that value moved recently? That question sounds trivial until you try to answer it across asset classes. A person who wants to compare the price of Bitcoin, the EUR/USD spot rate, an ounce of gold, a barrel of oil, a bushel of wheat, a share of Apple, the floor price of a blue-chip NFT collection and the auction value of a classic sports car normally has to open six or seven different websites, each with its own currency convention, its own refresh interval, its own jargon and its own paywall. Professional traders solve this with a terminal subscription that costs more per year than most households spend on electricity. Everyone else improvises.

We built USD Euro 360 as an attempt to close that gap using nothing but public data. Every market page on this site pulls from openly documented public application programming interfaces, normalises the results into a consistent format, converts them into both USD and EUR where a conversion is meaningful, and displays them with a visible indication of where the number came from and how fresh it is. There is no login wall in front of the market data, no subscription tier that unlocks "real" prices, and no artificially delayed feed designed to push you toward a paid upgrade. If we can display a number, we display it to everyone at the same time.

The second purpose of the site is educational. Raw price tables teach very little on their own. A number like "1.0842" means nothing to somebody who has never been told that a foreign exchange quote is a ratio between two currencies, that the first currency is the base, that the second is the quote, and that a move from 1.0842 to 1.0851 is nine pips. So alongside the data we publish written guides: explainers on how arbitrage spreads actually work once fees and withdrawal times are subtracted, primers on what drives the price of gold, walkthroughs of what a stock index really measures, articles about cosmetic and consumer product pricing across the Atlantic, and long career guides describing the qualifications behind the highest-paid professions. The intent is that a reader who arrives for a price stays for an explanation, and leaves understanding the market slightly better than when they arrived.

The third purpose is transparency about uncertainty. Financial websites have a bad habit of presenting every figure with the same confident typography, whether it came from a millisecond-accurate exchange feed or from somebody's rough estimate. We try not to do that. Where a number is a live market quote, we say so. Where a number is an estimate, a modelled value, an indicative auction range or an aggregate compiled from public reporting, we say that too, in the section describing it. You should always be able to work out how much confidence a given figure deserves.

2. Who the site is built for: the United States and Europe

USD Euro 360 is written and maintained primarily for readers in the United States and in Europe, with particular emphasis on the euro area. That focus is not accidental and it shapes almost every design decision on the site.

Why these two regions

The US dollar and the euro are the two most widely held reserve currencies on earth and together they sit on one side of the overwhelming majority of global foreign exchange turnover. Almost every commodity that matters — crude oil, gold, silver, copper, wheat, corn, coffee, cocoa — is quoted internationally in dollars. Almost every European household budget, salary, mortgage and grocery bill is denominated in euros or in a currency that tracks the euro closely. A reader in Boston and a reader in Berlin are therefore looking at the same global market through two different currency lenses, and the single most useful thing a site like ours can do is show both lenses side by side without making anybody do mental arithmetic. That is literally where the name comes from: USD and EUR, seen from every angle.

What that focus means in practice

• Language. The entire site is published in English. Every page, every navigation label, every article and every chart axis. We do not run machine-translated regional editions, because a mistranslated financial term is worse than no translation.
• Reference currencies. USD and EUR are first-class citizens everywhere. Where an asset is natively quoted in one, we show the other alongside it using a live reference rate rather than a stale hard-coded constant.
• Equity coverage. Our stock coverage centres on large, liquid, widely followed United States listings and on the major European indices, because those are the instruments our readers actually encounter in retirement accounts, index funds and news coverage.
• Foreign exchange reference. Our core FX rates derive from European Central Bank reference data, which is the same public benchmark used across the euro area for accounting, invoicing and reporting purposes.
• Regulatory tone. We assume our readers live in jurisdictions where financial promotion is regulated, where unlicensed advice is unlawful, and where consumer protection expectations are high. We therefore behave as an information publisher, not as a promoter.

None of this means readers elsewhere are unwelcome. A very large share of our audience reads from outside these two regions, and public market data is public everywhere. But we want to be honest that local exchange availability, local tax treatment, local settlement conventions, local retail pricing and local consumer protection rules may differ substantially from what our pages assume. If you are reading from outside the United States or Europe, treat our figures as international reference values rather than as your local price.

3. What this site is not: no purchases, no brokerage, no custody

This is the single most important section on this page, so it is stated without hedging: you cannot buy anything on USD Euro 360, and USD Euro 360 will never ask you for money, for funds to deposit, or for access to any account you hold elsewhere.

Concretely, USD Euro 360 is not any of the following:

• Not an exchange. We do not match buyers and sellers, we do not operate an order book, and no trade you place anywhere else passes through us.
• Not a broker or dealer. We do not route orders, we do not hold client accounts, and we earn nothing when you transact.
• Not a custodian or wallet. We never hold your fiat currency, your crypto, your securities or your private keys. We do not ask for a seed phrase, a private key, an exchange API key with trading permissions, or your banking credentials. Any website or message that claims to be USD Euro 360 and asks you for those things is fraudulent, and you should report it to us.
• Not a payment processor or money transmitter. No funds move through this site in any direction.
• Not a signals service, copy-trading platform, or managed fund. There is no paid group, no premium channel, no bot subscription and no portfolio management product. If someone offers you one in our name, it is not us.
• Not a licensed financial adviser. We are not registered as an investment adviser, financial adviser, or investment firm in any jurisdiction, and we do not hold ourselves out as one.

The portfolio page deserves a specific clarification, because its name can be misread. The portfolio tool on this site is a personal bookkeeping calculator. You type in what you already own and what you paid for it, and the page multiplies those figures by live prices so you can see an unrealised profit or loss. It does not connect to any brokerage or exchange, it cannot place trades, it cannot withdraw or deposit, and it does not verify that you actually hold anything. It is arithmetic on numbers you typed yourself, nothing more. The same applies to the price alert feature: an alert is a notification that a public price crossed a level you chose. It is not a trading instruction and it does not execute anything.

4. Why nothing here is investment advice

Every price, chart, table, ranking, calculator output, article and assistant reply on USD Euro 360 is published for general information and educational purposes only. None of it is investment advice. None of it is tax, legal or accounting advice. None of it is a personal recommendation, a solicitation, or an offer to buy, sell, subscribe for or underwrite any financial instrument, digital asset, commodity, collectible or currency.

The reason is structural, not merely legal boilerplate

Advice, in any meaningful sense, is personal. Whether an asset is suitable for a specific person depends on that person's income stability, existing debts, emergency savings, time horizon, tax residency and filing status, dependents, insurance coverage, pension arrangements, professional restrictions on trading, psychological tolerance for drawdown, and a dozen other facts. USD Euro 360 knows none of those things about you, asks for none of them, and stores none of them. A website that does not know whether you have three months of rent saved cannot responsibly tell you what to do with your money, and we do not pretend otherwise.

What follows from that

• Rankings on this site are descriptive, not prescriptive. A table sorted by 24-hour gain is a statement about what happened, not a suggestion about what to do next. Assets at the top of such a list are frequently the most volatile and the most likely to reverse.
• Our articles avoid buy, sell and hold calls entirely. When a guide explains a strategy, it is explaining how the mechanism works and what can go wrong with it, not urging you to use it.
• Historical performance shown in any chart on this site describes the past. It carries no predictive guarantee whatsoever. Markets that rose for a decade have fallen by more than half; assets that looked cheap have gone to zero.
• Prices can and do go down. Cryptoassets in particular are highly volatile, are unregulated or lightly regulated in many jurisdictions, may not be covered by investor protection or deposit guarantee schemes, and can lose their entire value. Leveraged products can lose more than the amount deposited.
• Before acting on anything you read here, consult a professional who is licensed in your jurisdiction and who has taken the time to understand your circumstances. Only ever risk money you can afford to lose entirely.

We would rather lose a reader who wanted a hot tip than give one. That is a deliberate editorial choice, and it applies to every corner of the site including the AI assistant, which is instructed to explain rather than recommend.

5. Every data source we use, section by section

We do not generate market prices. We do not invent them, model them, or smooth them into something prettier. Everything numeric on the market pages originates from a third-party public source, and this section lists those sources in full so that any reader can go and check a figure independently.

Cryptocurrency prices, market capitalisation and history

Our primary crypto source is CoinGecko's public API, which aggregates trades across a very large number of exchanges and publishes volume-weighted reference prices, circulating supply, market capitalisation, and one-hour, twenty-four-hour and seven-day percentage changes. When CoinGecko is unreachable or rate limited, the site fails over automatically to CoinPaprika, an independent aggregator with a comparable methodology. Individual coin detail pages draw their historical chart series from the same aggregator that supplied the spot quote, so a chart and its headline number remain internally consistent. Global statistics such as total market capitalisation, aggregate 24-hour volume and Bitcoin or Ethereum dominance come from the aggregator's global endpoint.

Crypto exchange tickers used by the arbitrage scanner

The arbitrage page does not use aggregated reference prices, because an aggregate average is precisely the wrong input for a comparison between venues. Instead it queries the public ticker endpoints of individual exchanges directly: Binance, Coinbase, Kraken, KuCoin, Bybit and OKX. These are read-only, publicly documented endpoints that require no account and no API key with trading permissions. Each exchange is fetched independently so that one slow or unavailable venue cannot block the others, and any venue that fails is simply omitted from that refresh cycle rather than being replaced with a stale value.

Foreign exchange rates

Our reference FX rates are built on the European Central Bank's daily reference rates, accessed through the Frankfurter public service, supplemented by a broader public rate provider for the long tail of world currencies so that we can express values across two hundred or so ISO 4217 codes. ECB reference rates are published once per business day and are a benchmark, not a transactable dealing price. Cross rates between two non-euro currencies are computed from their respective euro legs. The spread you are actually offered by a bank, card network, bureau de change or remittance service will always be worse than the reference rate, often by a meaningful margin, and our pages say so wherever a conversion is shown.

Equities, indices, futures and industrial metals

Share prices, index levels, exchange-traded commodity futures, energy contracts and industrial metals are sourced from Yahoo Finance's public quote endpoints, with additional coverage for selected United States symbols from Finnhub where available, falling back silently to Yahoo when that provider is unavailable or rate limited. These feeds are consolidated retail-grade quotes. They may be delayed relative to the exchange's own direct feed, they reflect the primary listing venue rather than every venue on which an instrument trades, and they are not a substitute for an exchange's official settlement or closing print.

Precious metals

Gold, silver, platinum and palladium spot values reference LBMA-referenced spot pricing through a public metals endpoint, with a cross-check against the tokenised gold market where a fallback is required. Spot metal is quoted per troy ounce for unallocated wholesale bullion. The retail price of a coin or a small bar always includes a fabrication and dealer premium above spot, and the price a dealer will pay you when buying back is always below spot.

Agricultural and soft commodities

Grains, softs and livestock come from the same public futures quote infrastructure as our other exchange-traded instruments. These are futures contracts for a specific delivery month, at a specific delivery location, for a specific grade. They are the global price discovery mechanism, but they are not the wholesale price in your country and they are emphatically not the retail shelf price, which additionally embeds processing, packaging, logistics, energy, labour, tariffs and retail margin.

NFT floor prices

Collection floor prices and volumes come from the public NFT endpoints of our crypto aggregator. A floor price is the lowest current asking price in a collection, which makes it a very noisy statistic: it can be moved by a single listing, it says nothing about the depth of real bids beneath it, it is denominated in a volatile base currency, and wash-trading has historically distorted reported volumes in this market. We display floors because readers ask for them, and we caution about them for the same reason.

Non-market sections: rankings, valuations and estimates

Several popular sections of the site are not market feeds at all, and it would be dishonest to present them as though they were. Billionaire net worth figures follow the methodology of public real-time billionaire trackers, which value listed holdings continuously from share prices while estimating private holdings, property and art from filings, reported transactions and disclosed stakes. Athlete earnings, transfer fees, salary benchmarks by profession, advertiser spending, classic and modern car values, trading card prices and luxury beauty retail prices are compiled from published reporting, auction results, industry surveys and public retail listings. These are estimates and compiled reference figures, they update far less frequently than a market feed, and they should be read as well-sourced approximations rather than as tradeable quotes.

6. Methodology: how raw feeds become the numbers on screen

Between a provider's response and the figure you read, a short and deliberately conservative pipeline runs.

1. Fetch. Requests are issued on a schedule appropriate to the asset class. Fast-moving crypto and FX refresh on a short interval; equities refresh frequently during their trading session; slow-moving reference and estimate data refreshes far less often. Requests are rate-limited on our side with a token-bucket scheduler so that we remain a well-behaved consumer of free public infrastructure.
2. Validate. Responses are shape-checked before use. A payload that is missing required fields, that returns a non-numeric price, or that returns an implausible value is discarded rather than rendered.
3. Fail over. If a primary source fails validation or is unreachable, the site switches to the designated backup for that asset class. The source actually in use is surfaced in the interface through a status badge and a live indicator, so a failover is visible to you rather than hidden.
4. Normalise. Symbols, decimals, percentage conventions and timestamps are standardised so that every table on the site speaks the same dialect, and USD/EUR conversions are applied from the live reference rate rather than a cached constant.
5. Diff and render. Only changed values are patched into the page, which is why prices update smoothly with a brief colour flash rather than causing the whole table to redraw. Large tables use row virtualisation so that thousands of rows remain responsive on modest hardware.
6. Degrade gracefully. If every source for a given field fails, we show the last known value clearly marked as stale, or we show nothing. We never fabricate a placeholder number and present it as live.

7. Accuracy, latency and known limitations

We work hard on accuracy and we still cannot promise it. Here is a candid list of the ways a number on this site can be wrong or misleading, so that you can calibrate accordingly.

• Latency. Nothing here is a co-located exchange feed. Depending on the asset class and the provider, a displayed figure may be seconds, minutes or, for once-a-day reference rates, hours behind the most recent transaction.
• Aggregation differences. Two honest aggregators can publish different prices for the same coin at the same instant because they weight different venues and pairs. A discrepancy between us and another site is usually methodology, not error.
• Provider outages and rate limits. Free public endpoints throttle and go down. When that happens you may see a stale badge, a gap, or a backup source.
• Reference versus dealable pricing. ECB FX rates, spot metal quotes and consolidated equity prices are benchmarks. Nobody will actually fill you at them.
• Thin and illiquid markets. Small-cap tokens, NFT floors, collectibles and auction assets can show dramatic percentage moves generated by a single small transaction.
• Estimates are estimates. Net worth figures, earnings tables, salary benchmarks and collectible valuations carry error bars that no user interface can adequately convey.
• Corporate actions. Splits, dividends, ticker changes, delistings, token migrations and rebrands can temporarily distort a series until the upstream provider adjusts it.

For any decision with real financial consequences, verify the number against the venue you will actually transact on, at the moment you intend to transact. That is the only price that binds anybody.

8. An honest explanation of the arbitrage scanner

The arbitrage page is the most easily misunderstood feature on the site, so it gets its own section. What the scanner does is mechanically simple: it fetches the current public ticker for the same trading pair on several exchanges at roughly the same moment and reports the percentage difference between the cheapest and the most expensive venue.

What that percentage is not is free money. A displayed spread is a gross, instantaneous, theoretical figure. Before a spread becomes profit, reality subtracts: taker fees on both the buy and the sell side; the bid-ask spread you actually cross, which the last-traded price conceals; slippage once your order is larger than the top of the book; network withdrawal fees; blockchain confirmation time during which the price moves; deposit crediting delays at the receiving venue; fiat rails and their own fees and cut-off times; withdrawal limits and identity verification requirements; the working capital needed to pre-fund both sides so you never actually have to move coins mid-trade; and, not rarely, a suspended withdrawal on precisely the asset and venue where the spread is largest. That last point is important — a persistently wide spread on one exchange is very often a symptom of a problem at that exchange rather than an opportunity.

Our net calculations subtract standard taker fees where we can, which is why our net column is smaller and less exciting than the gross number. Even so, treat the whole page as an observation of market fragmentation and an educational illustration of how price discovery differs between venues. It is not a trading signal, we do not suggest you act on it, and we earn nothing whether you do or not.

9. Estimated figures: billionaires, athletes, cars, collectibles and salaries

The sections covering the world's wealthiest individuals, the highest-earning athletes and transfer fees, classic and modern car values, trading card prices, luxury beauty pricing, the largest global advertisers and the highest-paying professions are compiled reference content. They exist because readers find them genuinely interesting and because they provide useful context for how capital, income and consumer pricing actually distribute in the United States and Europe. They are not live markets.

Net worth in particular is an estimate built on estimates. The listed-equity portion of a fortune can be tracked continuously because share prices are public and large stakes are disclosed, but private company stakes, real estate, art, aircraft, debt secured against shares, trusts, philanthropic transfers and family arrangements are opaque by design. Two reputable trackers routinely differ by billions on the same person. Salary benchmarks vary enormously by country, region, seniority, employer type and years of experience; the figures we publish are representative ranges rather than an offer any employer is making. Collectible and auction values reflect specific lots in specific condition sold on a specific day, and the identical model in different condition can be worth a small fraction of the headline. We present these figures because they are informative, and we label them as estimates because that is what they are.

10. Safety: why the site cannot harm or mislead you

A reasonable reader arriving at a finance website should be suspicious. Plenty of sites in this category are funnels into something predatory. So here is exactly why this one is not.

• There is nothing to sell you. There is no product, no subscription, no premium tier, no course, no signal group, no referral funnel to a leveraged offshore broker, and no affiliate link dressed up as a recommendation. When a section is sponsored, it is labelled as sponsored.
• We never ask for credentials that could cost you money. No seed phrases, no private keys, no exchange API keys with trade or withdrawal permission, no bank logins, no card details. There is no legitimate reason for us to want them, and we never will.
• No urgency, no hype, no guarantees. You will not find countdown timers, "limited spots", guaranteed returns, or promises about where a price is going. Any such claim made in our name is fraudulent.
• Sources are disclosed rather than obscured. This page names every provider, and the interface shows which source is live at any moment.
• Errors are corrected in public. When we get something wrong and a reader tells us, we fix it and we do not quietly pretend it never happened.
• Read-only by construction. The site technically cannot move money. It has no payment integration and no trading connectivity of any kind.

Being honest about the flip side: the site cannot protect you from decisions you make elsewhere. If you read a price here and then take excessive risk on an exchange, that outcome is yours. Our commitment is to give you accurate, well-sourced, clearly-labelled information and never to nudge you toward a transaction.

11. Privacy, accounts and the data we store

Market browsing on USD Euro 360 requires no account. You can read every price page, every article and every calculator without identifying yourself. Optional personal features — the portfolio bookkeeping tool, the watchlist and price alerts — store only what you type in, associated with your own session or account, and they contain no connection to any external financial institution. We do not sell personal data. Cookie preferences are requested through the consent banner, and advertising, where present, is served by third parties subject to their own policies as described on our privacy page. For the full statement see our Privacy Policy, our Terms of Use, and our Disclaimer.

12. Advertising, sponsorship and editorial independence

Running live market infrastructure costs money even when every data source is free, so the site may display third-party advertising. Advertising is how we keep every page open to every reader without a paywall. Two commitments constrain it. First, advertising is visually distinct from editorial content and clearly identifiable as advertising; we do not write articles that are secretly promotions. Second, no advertiser, exchange, broker, token project or brand has any influence over what we publish, how we rank an asset, which sources we choose, or what we write in a guide. Nobody can pay to appear higher in a table, because our tables are sorted by market data, not by relationships. If we ever publish genuinely sponsored editorial, it will carry an explicit label at the top of the piece.

13. The Financial Assistant and how we use AI

The site includes an AI assistant that can answer questions about market concepts and about the content of this site. It is grounded in a structured knowledge base describing every page and article here, and it is given a snapshot of current market data so that its answers reflect present conditions rather than stale training data. It is instructed to explain rather than to recommend, and it is instructed to decline to give personal financial advice.

Language models can nevertheless be confidently wrong. An assistant answer is not a verified editorial statement, it is not investment advice, and it should be checked against the underlying market page or a primary source before you rely on it for anything that matters. We use AI to help readers navigate and understand the site, never as an authority on what you should do with your money.

14. Editorial standards and corrections policy

Our written content is produced in-house in English. Guides are structured around a reader who is encountering the topic for the first time: define the term, explain the mechanism, show a worked example, then state the risks and the common mistakes. We avoid predictions, price targets and any framing that implies urgency. Where a claim is factual we attribute it; where a figure is an estimate we say so; where a topic is genuinely contested we present the disagreement rather than resolving it artificially.

When we are wrong, the correction policy is simple. Email us with the page and the problem. Factual errors are corrected as soon as we can verify the correction, data-source issues are investigated against the upstream provider, and substantive changes to an article are noted rather than silently applied. We would much rather receive a blunt correction than continue publishing a mistake.

15. A short glossary for new readers

Spot price

The price for immediate delivery, as opposed to a future date.

Bid and ask

The highest price a buyer will pay and the lowest a seller will accept. The gap between them is the spread, and it is a real cost of trading.

Slippage

The difference between the price you expected and the price you actually got, because your order consumed more than the top of the order book.

Market capitalisation

Price multiplied by circulating supply. A measure of aggregate size, not of money invested.

Base and quote currency

In EUR/USD, EUR is the base and USD is the quote; the number tells you how many dollars one euro buys.

Reference rate

An official benchmark published for accounting and comparison. Not a price you can trade at.

Floor price

The lowest current asking price in an NFT collection. A listing, not a completed sale.

Taker fee

The commission charged when your order executes immediately against a resting order.

Troy ounce

The unit precious metals are quoted in, about 31.10 grams, heavier than a standard ounce.

Volatility

How violently a price moves. High volatility means large gains and large losses are both likelier.
