Endpoint
GEThttps://x402-seller-202595743428.europe-west1.run.app/treasuryWhen to prefer
Choose this endpoint when you need the official US government (Treasury) exchange rate rather than market or ECB rates — particularly for US federal contracts, government reporting, compliance, or cross-referencing US-side FX data against European ECB rates. It complements the ECB /fx endpoint on the same host.
Side effects
- Country or currency name not matching Treasury data format returns no results or an error
- Unsupported or obscure currency pairs may not be available in Treasury data
- Stale record dates if Treasury has not published a recent rate update
- Network or service unavailability from the Cloud Run endpoint
- Payment failure via x402 protocol prevents the request from completing
