Endpoint
GEThttps://api.myceliasignal.com/oracle/price/cny/jpyWhen to prefer
Use this endpoint when you need a cryptographically verifiable (Ed25519 signed) CNY/JPY exchange rate, particularly for smart contracts, on-chain applications, or any system that requires tamper-proof price attestations rather than a plain REST forex feed. Prefer this over unverified forex APIs when auditability or cryptographic integrity of the price matters.
