Need a fresh check?

Checks are bought by AI agents over x402, not in the browser. Give your agent this address — any x402 client can pay ($0.01 in USDC on Base, no account):

GET https://402registry.com/buy/one?site=https://payapi.market/

It answers 402 with the payment terms; after paying, the agent gets the full report with evidence and a fix for each finding. What a check is and how to verify the terms before paying.
