Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/treasury-fxWhen to prefer
Use this endpoint when you need authoritative, official U.S. government foreign exchange rates for federal financial reporting, compliance, or auditing purposes — not market rates or real-time trading rates. Prefer this over commercial FX APIs when official government-sourced quarterly rates are specifically required.
Side effects
- Invalid or unrecognized country name returns an error or empty result
- No data available for requested quarter returns empty or null response
- Network timeout or service unavailability returns a 5xx error
- Malformed query parameter may return a 400 bad request
