Endpoint
GEThttps://api.x402node.dev/forex/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live exchange rate for any arbitrary currency pair — including less common pairs beyond USD/EUR/JPY — and optionally want the converted value for a specific amount in a single call. Unlike sibling endpoints that are hardcoded to specific pairs, this endpoint accepts any base and quote currency codes as parameters, making it the most flexible option for dynamic or user-specified currency conversion needs.
Side effects
- Unsupported or invalid currency code returns an error response
- Missing required base or quote parameter returns a 400-level error
- Rate data temporarily unavailable returns a service error
- Payment of 0.006 USDC not completed results in 402 Payment Required response
- Malformed currency code (e.g. typo) returns no matching rate
