Endpoint
GEThttps://built-with-productos-xszv.vercel.app/v1/fx-rate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, low-cost, pay-per-call FX rate lookup with no API key setup, especially in agentic or automated workflows using x402/MPP micropayments. Ideal for spot-rate queries where sub-second latency and minimal friction matter more than historical data or high-frequency streaming.
Side effects
- Invalid or unsupported 3-letter currency code returns an error
- Missing base or quote parameter results in a validation error
- Payment not provided or insufficient triggers a 402 Payment Required response
- Network or upstream FX data source unavailability may cause a 503 or timeout
