Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/gbp/usdWhen to prefer
Choose this endpoint when you need a cryptographically verifiable GBP/USD forex rate — particularly for smart contract inputs, DeFi protocols, or any use case requiring tamper-proof price attestation via Ed25519 signature. Prefer over unsigned REST forex APIs when on-chain verifiability or non-repudiation is required.
Side effects
- Price feed unavailable or stale — service may return an error if upstream forex data cannot be fetched
- Payment not received or invalid — x402 payment of $0.01 USDC required; missing or invalid payment returns 402
- Rate limiting — excessive requests may be throttled
- Signature verification failure — client should verify Ed25519 signature against Mycelia Signal's public key
