Documentation

The Forex Feed API serves live and historical exchange rates over HTTPS in a consistent JSON envelope. Every endpoint is a simple GET request authenticated with a Bearer API key — no SDKs required, though everything works with any HTTP client in any language.

Your first requestbash

curl "https://forex-feed.com/api/v1/latest?symbols=EUR,GBP,JPY" \
  -H "Authorization: Bearer ff_live_YOUR_KEY"
