Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usd/jpyWhen to prefer
Choose this endpoint when you need a cryptographically verifiable (Ed25519-signed) USD/JPY exchange rate — especially for on-chain smart contract use, trust-minimized financial applications, or any context where you need to prove the price data is authentic and unmodified. Prefer it over unsigned REST FX APIs when attestation and auditability matter.
Side effects
- Payment not received or x402 payment flow fails — endpoint returns 402 Payment Required
- Oracle data source unavailable — stale or missing price returned
- Invalid Ed25519 signature if provider key changes — signature verification failure downstream
- Network timeout if price feed is momentarily unavailable
- Rate limit exceeded — too many requests in a short window
