Everything a payments business needs from a currency data provider, on one key and one agreement.
Bid, ask and mid for 150+ currencies, 4,000+ pairs and 50+ cryptocurrencies. Live on every call over REST: poll every minute for a customer dashboard or every second at checkout. WebSocket streaming is available as a separately priced alternative.
Daily open, high, low and close back to 1990, hourly and minute bars, and tick data since 2016. Build averages over any period, reconcile invoices and evidence the rate you showed on any day.
Convert any amount between two currencies at the live rate in one call, for checkout totals, quotes and invoices. Same symbols and the same key as the rates.
REST and WebSocket, SDKs for Python, Kotlin and Go, and a licence that covers display to your signed-in customers in your app, rates on invoices and statements, and all internal use. 99.99% availability SLA.
Built for companies that pay for currency data today and want faster rates, clearer terms and a licence that already covers the app and the back office.
Live rates for signed-in customers in your app, at checkout and on their invoices, quotes and statements, plus any use inside the business. Public web pages are a separate licence; ask us if you need one.
Elsewhere, anything fresher than daily sits behind an enterprise tier or a paid add-on. Here REST is live on every call: poll it every minute for a customer dashboard or every second at checkout, on any agreement.
WebSocket pushes every bid and ask tick for quote engines that would rather not poll. It is an alternative to REST, licensed and priced separately, so you only take it if you need it.
Set your own margin off a real two-way market instead of a single mid-rate. The same bid and ask come back over REST and WebSocket.
Minute, hourly and daily history back to 1990, plus tick data since 2016, to evidence the rate you showed at the time.
You keep your rate service, your margin and your rounding. We replace the feed underneath it.
per_quote_ts=true every quote carries its own timestamp too, so your page can say "Updated 14:02 UTC" and your logs can prove it.
One call a minute with up to 10 pairs in it: 43,200 calls a month, the equivalent of 432,000 per-currency updates on an API that meters each currency separately. That cadence already passes the 10,000-call entry tier of the request-metered APIs we compared, before a second server or a staging environment.
Three steps to put our rates behind your app, checkout and invoicing, with your current feed still running while you check.
ISO codes, the same ones you use today. 150+ fiat currencies plus metals and 50+ cryptos, so the exotic corridors come along.
One GET /live per minute, or per second at checkout, replaces your current call. Bid, ask and mid come back in one JSON body with the timestamp.
Poll every 60 seconds for display and every second for checkout, all over REST. WebSocket streaming is available as an alternative, priced separately.
Public plans of two widely used currency data APIs, October 2026, against ours. Lower price, better rate.

|---|---|---|
| Minute-by-minute rates | Enterprise tier, or a paid add-on on self-serve plans | Included on every agreement |

| Monthly request cap | 10,000 to 150,000 calls on self-serve plans | Sized to your refresh, up to 10 pairs per call. Once a minute is about 43,000 calls a month, the equivalent of 432,000 per-currency updates; once a second about 2.6 million calls, whatever your traffic |
| Two-way prices | Mid-rate; bid and ask in beta or on higher tiers | Bid, ask and mid on every pair |
| Showing rates to your customers | Internal use on standard plans; wider display by partner or enterprise programme | In-app display to signed-in customers and internal use included |

Yes, to signed-in customers in your app and at checkout, on their invoices, quotes and statements, and anywhere inside the business. Public web pages are not covered by this licence; ask us if you need one.
As often as the screen needs. A customer dashboard polls /live every 60 seconds, up to 10 pairs per call; a checkout polls every second. Cache the response and serve every customer from the cache. Each response carries the time it was served, and per_quote_ts=true adds a timestamp to every quote, so the screen can show when each rate was last updated.
No. REST is live on every call and can be polled every second, which is how most payment platforms run. WebSocket is an alternative that pushes every bid and ask tick as it happens, with p99 delivery under 20 ms, for quote engines that prefer pushes to polls. It is licensed and priced separately from REST. See the WebSocket docs.
150+ currencies, including the emerging-market corridors that remittance runs through, plus precious metals and 50+ cryptocurrencies: more than 4,000 pairs in total, each requestable directly. The full list is on the symbols page.
Bid, ask and mid on every pair, over REST and WebSocket. Price your margin off the side you deal on and show the mid to customers if that is what your product displays.
Minute, hourly and daily history back to 1990 and tick data since 2016, on the same key. Evidence the rate you showed at any moment for audits, VAT returns or a customer dispute. See historical data.
Yes. Run both feeds side by side during the trial and compare rate by rate. A trial key takes a few minutes to set up; when you are ready to move over, send your currency list and we will come back with a quote.
