Endpoint
POSThttps://206-81-14-131.sslip.io/svc/currency-rates/sample?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-use FX rate lookups without the overhead of registering for a traditional API key. Ideal for AI agents that need occasional currency rate data for financial calculations, invoice generation, or payment conversion checks, especially when paying with USDC on Base via x402. Best for low-volume, on-demand lookups rather than high-frequency streaming FX data.
Side effects
- Payment not included or insufficient USDC balance — returns 402 Payment Required
- Invalid or unsupported currency codes in request — may return empty or error response
- Network timeout or service unavailability — returns 5xx error
- Malformed POST body — returns 400 Bad Request
