How this service works
aave-v3-arbitrum-usdc: USDC supply APR, time-weighted over 2026-09-28→2026-09-29, 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
Returns a signed artifact containing the time-weighted USDC supply APR for Aave V3 on Arbitrum over the 2026-09-28 to 2026-09-29 window. The artifact includes the computed APR value, the date range, a SHA256 content hash, and a secp256k1 cryptographic signature. The schema and all figures can be recomputed and verified offline without any further API calls or trust in the provider.
Example use cases
DeFi yield audit trail for treasury
“I need a tamper-proof record of the USDC supply APR on Aave V3 Arbitrum for September 28 to 29 2026 — something with a cryptographic signature I can verify independently for our treasury audit.”
On-chain rate data for a structured product
“Pull the signed, time-weighted USDC APR from Aave V3 Arbitrum for the Sep 28–29 2026 period so we can use it as a reference rate in our DeFi structured product — I want the secp256k1 signature so we can attest the figure without calling your API again.”
Verifying DeFi yields without trusting a provider
“Get me the Aave V3 Arbitrum USDC supply APR artifact for Sep 28 to Sep 29 2026 — I want to recompute the time-weighted rate myself from the published data and check it against the signature, not just take someone's word for it.”

Prefer this endpoint when you need a cryptographically attested, offline-verifiable DeFi yield figure for the specific Aave V3 Arbitrum USDC pair on the 2026-09-28 to 2026-09-29 window, and want to avoid the cost and complexity of fetching contracts, decoding ray-scaled rates, sampling the series, and computing the time-weighted average yourself. Ideal for audit, compliance, or trust-minimized financial workflows where independent verification of the math and signature matters.
Side effects
- Payment not received or x402 payment flow fails — endpoint returns 402 with payment requirements
- Artifact hash mismatch — requested SHA256 not found, returns 404
- Service temporarily unavailable on fly.dev infrastructure — returns 503
- Rate or timeout errors if the Fly.dev deployment is cold-starting
