How this service works
aave-v3-arbitrum-usdc: USDC supply APR, time-weighted over 2026-09-23→2026-09-24, signed. Cheaper than the agent turns you'd burn finding the contracts, decoding ray-scaled rates, sampling the series, and time-weighting it — you trust the math, not us. Verify it offline — schema, every published figure recomputed, and the secp256k1 signature — with no API call and no trust in us.
Output
A signed artifact containing the time-weighted USDC supply APR for Aave V3 on Arbitrum over the 2026-09-23 to 2026-09-24 window. The response includes the computed yield rate (derived from ray-scaled on-chain data), sampling methodology, and a secp256k1 cryptographic signature over the result, allowing full offline verification of both the math and the authenticity of the figure without any additional API calls.
Example use cases
Auditing DeFi yield for accounting
“Pull the verified USDC supply APR on Aave V3 Arbitrum for September 23–24 2026 — I need the signed artifact so our finance team can reconcile yield income without trusting a third party's math.”
Comparing historical lending rates

Prefer this endpoint when you need a cryptographically attested, time-weighted DeFi yield figure for Aave V3 USDC on Arbitrum for the specific 2026-09-23 to 2026-09-24 window, without spending agent compute decoding raw ray-scaled contracts or sampling on-chain data yourself. It is ideal for audit trails, oracle inputs, or compliance workflows that require offline verifiability via secp256k1 signatures rather than trusting a live API response.
Side effects
- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Artifact hash mismatch — SHA256 in the URL does not correspond to a stored artifact, returns 404
- Network or hosting unavailability on fly.dev infrastructure — returns 5xx
- Rate or signature verification fails offline if the local recomputation diverges from the published schema
