How this service works
All DeFi lending rates — 7 protocols, 7 chains, on-chain — Ed25519 signed attestation
Output
A cryptographically signed (Ed25519) dataset containing current lending and borrowing yield rates for 7 DeFi protocols across 7 blockchain networks, with on-chain attestation for trustless verification. Includes per-protocol, per-chain rate breakdowns suitable for use in smart contracts or risk models.
Example use cases
Example prompt
“Can you pull the latest DeFi lending and borrowing rates across all 7 protocols and 7 chains from MyceliaSignal's oracle — I want the Ed25519-signed attestation so I can verify the data is authentic before feeding it into my risk model.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/defi/yield/allWhen to prefer
Choose this endpoint when you need a comprehensive, cryptographically attested snapshot of DeFi lending and borrowing rates across multiple protocols and chains in a single call. Prefer this over per-protocol scraping when you need Ed25519-verifiable data suitable for on-chain consumption, risk models, or cross-protocol yield comparison. Ideal for agents building yield optimizers, liquidation monitors, or portfolio dashboards that require trustless multi-chain rate data.
Side effects
- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Upstream on-chain data temporarily unavailable — returns 503 or stale data with degraded freshness signal
- Invalid or missing authentication — returns 401
- Network timeout fetching data from one or more chains — partial data or error response
