How this service works
USDC rate comparison across all DeFi lending protocols — Ed25519 signed attestation
Output
A cryptographically signed (Ed25519) payload listing current USDC lending/supply APY rates across multiple DeFi lending protocols (e.g. Aave, Compound, Morpho), enabling verifiable rate comparison to identify the best yield opportunity for USDC.
Example use cases
Example prompt
“Show me a signed comparison of USDC lending rates across all DeFi protocols right now — I want to know which one is offering the best yield.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/defi/yield/compareWhen to prefer
Use this endpoint when you need a cryptographically attested, multi-protocol USDC yield comparison in a single call — ideal for DeFi portfolio optimizers, yield aggregators, or smart contract systems that require signed oracle data to trustlessly verify rates on-chain or off-chain.
Side effects
- Rate data unavailable due to RPC/node issues — returns 503 or partial data
- Invalid or expired Ed25519 signature if signing key rotated
- Payment of 0.05 USDC not received — returns 402 Payment Required
- Protocol data source lag causing stale rates
- No query params required but malformed request returns 400
