Technical details
Endpoint
GEThttps://6xrkjcfa3yrzvefcpvanurzou4.srv.us/api/fx-rate?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a real-time FX rate that is cross-validated across three independent sources rather than relying on a single provider, and when you want transparency about source divergence via the basis-point spread. It requires no API key or account setup and is well-suited for agents needing trustworthy spot rates for financial calculations, invoicing, or arbitrage detection.
Side effects
- Invalid or unrecognized currency pair symbols returns an error
- One or more upstream FX sources temporarily unavailable may affect cross-check reliability
- Missing required query parameters (base or quote currency) returns a 400-style error
- Rate limit or payment failure (x402) blocks response if USDC payment not completed
