apix402 — Onchain Verified Data

api402x.com · api402x.com

Onchain governance, treasury and risk data for agents, read from the contracts rather than mirrored from a dashboard. DAO proposals cross-checked between Snapshot and each DAO's own Governor contract; whether a known proposal actually executed rather than merely succeeded; Hedgey and Sablier vesting plans read from the contract; a beneficiary's outgoing transfers before their cliff; Gnosis Safe owner, threshold and module drift compared against the same Safe's configuration at an earlier block; Chainlink and Pyth staleness judged per feed against each feed's own measured cadence; and Aave wstETH depeg exposure recomputed independently of the published health factor. $0.01-$0.05 USDC per call on Base, x402 v2, free /preview on every paid route, no signup and no API key.

No protocolVersion in card.

            How to earn +10 points

Stabilise uptime

We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
