How this service works
GBP/JPY forex exchange rate — British pound to Japanese yen — Ed25519 signed attestation
Output
Returns a JSON object containing the currency pair domain (GBPJPY), a public key for signature verification, a canonical price string encoding the rate, sources (e.g. frankfurter, norgesbank), aggregation method (median), a Unix timestamp, and a base64-encoded Ed25519 signature over the canonical string — allowing downstream consumers to cryptographically verify the attestation.
Example use cases
Example prompt
“What is the current GBP/JPY exchange rate with a cryptographic Ed25519 signature so I can verify it came from a trusted source?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/gbp/jpyWhen to prefer
Choose this endpoint when you need a cryptographically verifiable GBP/JPY forex price that can be proven to originate from a specific oracle (e.g. for smart contracts, on-chain settlement, or audit trails). It aggregates multiple sources using a median to reduce manipulation risk and provides an Ed25519 signature for tamper detection. Prefer over plain REST forex APIs when trust and verifiability matter.
