Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usdc/usdWhen to prefer
Use this endpoint when you need a cryptographically verifiable, signed price attestation for USDC/USD — particularly useful for DeFi applications, smart contract triggers, or any workflow requiring provable stablecoin peg data rather than a raw unsigned price. Prefer over unsigned feeds when auditability or on-chain verification is required.
