Cross-border B2B payments are typically priced as a margin over a reference rate plus a wire or transfer fee. The reference rate itself is a midpoint, not a tradeable price — but documenting it at the time a payment is made is a common control for finance and treasury teams.
fxmap.app publishes mid-market reference rates with hourly cadence, 30-day history, and a free public JSON API with a stable response envelope. Finance teams use it to benchmark provider quotes, reconcile invoices denominated in foreign currency, and surface FX context on internal dashboards.
When a payments-platform partner CTA appears below, it is an affiliate link. fxmap may earn a commission, and that commission has no influence on the reference rates we publish.

Frequently asked questions
- Can fxmap's rates be used as a reference rate for invoicing or bookkeeping?
- fxmap publishes the underlying rate with a timestamp and source. Many finance teams use it as an informational benchmark, but whether it is acceptable as the rate of record depends on your jurisdiction's accounting and tax rules. Confirm with your accountant or auditor.
- Is the API stable enough to integrate into production?
- The /api/v1 surface is in public beta with a stable JSON envelope (data + meta.source / last_updated / disclaimer) and a soft per-IP rate limit. Free use requires visible attribution. Production users should bring their own retry, cache, and fallback logic — see the developer docs for details.
- Does fxmap quote the rate my payment provider will give me?
- No. The rate your provider quotes will include a margin and any applicable fees. fxmap's mid-market reference rate is the benchmark you compare that quote against to see the spread.
- Does fxmap provide hedging or FX risk advice?
- No. fxmap is an information service. We publish reference data; we do not provide regulated FX advice, hedging recommendations, or transaction execution.
- How do I cite fxmap when documenting a rate in our records?
- Cite the source URL, the as_of timestamp returned by the API, and (where applicable) the upstream provider listed in meta.source. Free use of the v1 API requires a visible 'Powered by fxmap.app' attribution where the data is shown.
Need a tradeable price?
fxmap.app does not execute transactions. To send, spend, or receive money in a foreign currency, use a regulated provider and verify the quoted rate at the moment you book.
