Best Forex Data APIs (2026)
Every vendor we track that covers forex (currency pairs), sorted by lowest listed paid plan. Forex is often bundled with stocks or crypto, so the cheapest plan that includes FX may not be a forex-only plan. Check whether real-time FX and WebSocket streaming are included at the tier you pick.
