The responses are flat JSON, or CSV, XML and Excel on the same URL, and there are official SDKs for [JavaScript, Python, PHP, Go and Rust](https://allratestoday.com/docs/sdks/). ## What the forex API returns, and what it does not | You get | You do not get | | --- | --- | | Mid-market rates for 160+ currencies, any pair, any direction | Bid/ask spreads or dealable quotes | | A refresh every 60 seconds with a `time` field on every rate | Tick-by-tick streaming or a WebSocket feed | | Rates on a date and daily series over the last 365 days (paid) | Intraday OHLC candles | | Official fixings from [122 central banks and 4 tax authorities](https://allratestoday.com/central-bank-rates-api/institutions/), keyless | Order books, volumes or futures | | JSON, CSV, XML and XLSX from the same endpoints | Execution — this is data, not a broker | That makes it the right fit for pricing, conversion, invoicing, reporting, dashboards and analytics on daily data. If you are building a trading engine that needs dealable quotes or sub-second ticks, you need a broker or market-data vendor instead, and this page will not pretend otherwise. ## Quick start 1. [Create a free account](https://allratestoday.com/register/) and copy the key that begins with `art_live_`. 2. Request one or several pairs in a single call: ``` curl "https://allratestoday.com/api/v1/rates?source=EUR&target=USD,GBP,JPY" \ -H "Authorization: Bearer art_live_your_key" ``` ``` [ { "rate": 1.12145, "source": "EUR", "target": "USD", "time": "2026-10-19T14:27:01+0000" }, { "rate": 0.84215, "source": "EUR", "target": "GBP", "time": "2026-10-19T14:27:01+0000" }, { "rate": 177.675, "source": "EUR", "target": "JPY", "time": "2026-10-19T14:27:01+0000" } ] ``` One row per target, each with the rate and the minute it belongs to. Add `&amount=10000` to have the API return the converted figure as well, and `&format=csv` for a file. With the SDKs: ``` import AllRatesToday from '@allratestoday/sdk'; const fx = new AllRatesToday({ apiKey: process.env.ALLRATES_API_KEY }); // Latest FX rates, several pairs in one call const { rates } = await fx.latest({ base: 'EUR', symbols: ['USD', 'GBP', 'JPY'] }); // Convert an amount at the live rate const { result } = await fx.convert('EUR', 'USD', 10_000); ``` ``` from allratestoday import AllRatesToday fx = AllRatesToday(api_key="art_live_your_key") data = fx.latest(base="EUR", symbols=["USD", "GBP", "JPY"]) print(data["rates"]) # {'USD': 1.12145, 'GBP': 0.84215, 'JPY': 177.675} quote = fx.convert("EUR", "USD", 10_000) print(quote["result"], quote["rate"]) ``` ## FX history and time series A dated lookup returns the mid-market rate for that day; a range returns one row per day, ready for a chart or a month-end revaluation. History is on the [paid plans](https://allratestoday.com/pricing/) and is metered by volume (one unit per currency per month of data), so a year of EUR/USD is twelve units, not 365 calls. ``` # One pair, one row per day (paid plans) curl "https://allratestoday.com/api/v1/rates?source=EUR&target=USD&from=2026-09-01&to=2026-09-30" \ -H "Authorization: Bearer art_live_your_key" # Or as a spreadsheet curl "https://allratestoday.com/api/v1/rates?source=EUR&target=USD&from=2026-09-01&to=2026-09-30&format=xlsx" \ -H "Authorization: Bearer art_live_your_key" -o eurusd-september.xlsx ``` ## Official fixings next to the market rate Most forex APIs stop at the market rate. Finance teams also need the number a central bank published for the day, because that is the one tax, customs and audit rules cite. The same API serves the latest table from [122 central banks and 4 tax authorities](https://allratestoday.com/central-bank-rates-api/institutions/) with no key, and dated tables and history on the [Official Rates plan](https://allratestoday.com/pricing/#official). ``` # The ECB's daily fixing — no key curl "https://allratestoday.com/api/open/central-bank/ecb" ``` Swap `ecb` for `fed`, `boe`, `rbi`, `boj` or any code on the [central bank rates API](https://allratestoday.com/central-bank-rates-api/) page. The difference between the two numbers, and when each applies, is explained in [official vs market rate](https://allratestoday.com/blog/official-exchange-rate-vs-market-rate/). ## Endpoints | Endpoint | Returns | Key | | --- | --- | --- | | `/api/v1/rates?source=&target=` | Live mid-market rate for one or many pairs; add `amount` to convert | Free | | `/api/v1/rates?…&time=YYYY-MM-DD` | The rate on a past date | Paid | | `/api/v1/rates?…&from=&to=` | Daily time series for one pair | Paid | | `/api/v1/symbols` | The 160+ supported currencies with names and symbols | Free | | `/api/open/central-bank/{bank}` | Latest official table from a central bank or tax authority | None | | `/api/v1/central-bank/{bank}/history` | Official rates back to the bank's first table | Official plan | | `/api/open/geo` | The caller's country and currency from their IP | None | Every table endpoint accepts `&format=json|csv|xml|xlsx`. The full reference is in the [documentation](https://allratestoday.com/docs/) and the [OpenAPI spec](https://allratestoday.com/api-reference/); the [playground](https://allratestoday.com/playground/) runs any of these in the browser with your key. ## Free tier and plans - **Free:** no card.

Our own fit is above; if you need ticks or spreads, those pages name who does. ## Frequently asked questions ### Is this a real-time forex API? Rates are mid-market and refresh every 60 seconds, and every response carries the time the rate belongs to. That is real-time for pricing, conversion, dashboards and reporting. It is not a tick feed: there is no streaming connection and no bid/ask or order-book data. ### Is there a free forex API tier? Yes. A free key is non-commercial and needs no credit card. Live rates and conversion work on the free plan; dated history and time series need a paid plan, from €4.99 a month. ### Which currencies does the forex API cover? Over 160 currencies, every pair in either direction, with the list available from /api/v1/symbols. Official central-bank tables add the currencies each bank publishes, including some that have no liquid market quote. ### How far back does FX history go? Market-rate history is available by date or as a daily series over the last 365 days on paid plans. Official central-bank history goes much further: the ECB reference rate back to 1999, for example. ### What is the difference between the forex rate and the official rate? The forex rate is what the market trades at now; it moves all day. The official rate is the figure a central bank publishes once a day and never revises. Pricing uses the first; tax, customs, accounting and contracts usually cite the second. The API returns both. ### Can I use the forex API from a browser? The keyed market-rate endpoints do not send CORS headers, so call them from your server. The keyless official-rate endpoints are CORS-open and can be fetched directly from a web page. ## Start with the forex API Free key in 30 seconds. 160+ currencies, 60-second refresh, no credit card.
