Technical details
Endpoint
GEThttps://api.cortexcloud.org/x402/v1/fx/list?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover which FX currency pairs or financial instruments are available via Cortex Cloud before querying rates or prices. Prefer this over hardcoding pair names. Good for building dynamic UIs or validating instrument support. Choose this over alternatives if you are already paying per-call in USDC on Base and want a no-subscription, no-API-key workflow.
Side effects
- Empty or malformed response if the service is unavailable
- 402 Payment Required if USDC payment on Base is not properly submitted
- Sparse schema means no documented error codes — unknown failure structure
- Properties filter may silently accept invalid values without returning an error
