v3 is in preview. If you’re starting a new integration, consider migrating to v3 — v3 introduces stable error codes, bare-resource responses, and a /v3/fx/ surface.
OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We provide financial institutions with access to FX and stablecoin liquidity and same-day settlements globally. Traders and developers can use the OpenFX API suite to automate the end-to-end trading and settlement process: deposit detection, continuous quote streaming, low-latency trade execution, and settlement for multiple fiat currencies and stablecoins.
v2 is the current generation of the OpenFX API. If you are integrating from v1, see the migration guide for the breaking changes (most notably required Idempotency-Key headers on POST endpoints).

​
