Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/gbp/cnyWhen to prefer
Use this endpoint when you need a cryptographically verifiable GBP/CNY exchange rate — particularly useful for smart contracts, DeFi applications, or any workflow requiring tamper-proof price data with an Ed25519 signature. Prefer this over unauthenticated REST forex APIs when auditability and attestation are required.
Side effects
- Payment not included or invalid — HTTP 402 returned requiring $0.01 USDC via x402 protocol
- Rate data temporarily unavailable — upstream price feed outage
- Invalid Ed25519 signature verification on the client side if public key mismatch
- Network timeout if oracle backend is unresponsive
