Check the wash-traffic risk of Algorand x402 endpoints before your agent pays them.
📊 The x402 Trust Index — our free public data site: dated Bazaar Wash Report snapshots (Base) + reseller-signal audits for 38 API brands.
Leaderboards for machine-payable APIs rank by claimed volume, which is easy to inflate — self-dealing loops, fresh-wallet farms, metronomic bots. Provenance reads public on-chain payments and gives your agent a statistical estimate of whether an endpoint's revenue looks organic or manufactured, so it can decide before sending USDC. This server scores Algorand payees; the public data site's report covers Base. Scores are one operator's estimates — the methodology publishes the weights, the limits, and what has not been validated yet.

Then ask your agent: “check the wash risk of Algorand endpoint <ADDRESS>”.
The hosted Provenance engine indexes USDC (ASA 31566704) payments on Algorand mainnet, enriches payer wallets (age, first funder, asset diversity, rekey auth-addr), clusters them (union-find over funding + shared-key links), and runs 8 wash-detection signals. Scores are point-in-time snapshots, anchored on-chain for tamper-evidence. Methodology: signals, not accusations — a high score means the revenue pattern is consistent with self-dealing, not that the operator is guilty of anything.
