Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usd/cnyWhen to prefer
Choose this endpoint when you need a cryptographically attested, tamper-evident USD/CNY exchange rate — particularly for smart contract inputs, on-chain oracle feeds, or any workflow requiring verifiable data provenance. Prefer it over unsigned REST forex APIs when trust and auditability of the price data are critical.
Side effects
- Payment not provided or insufficient — x402 payment required error
- Rate temporarily unavailable due to upstream data source outage
- Invalid or expired Ed25519 signature in edge cases
- Network timeout or service unavailability returning 5xx
