Locus public pay-per-use API

Checkup for x402 buyer clients. Pay once and get a field-by-field diagnosis of the payment your client signed (amount, recipient, validity window, clock offset, nonce, EIP-712 signature) and of the request that arrived, plus the facilitator's verify and settle results. Base mainnet payments get the full diagnosis; Base Sepolia payments get a preview with the status of each check only.

Audit your x402 endpoint before buyers hit it. Checks that it answers 402 on the right method, that the payment options can actually be signed (EIP-712 domain of the token matches extra.name and extra.version), that the resource URL is the https URL buyers call, and that /openapi.json and /.well-known/x402 match. Includes the CDP validate verdict, whether the CDP Bazaar lists the endpoint, its pay

PII sanitization — pay-per-call entry point

Check an x402 seller before you pay it. Probes the endpoint now, checks that its payment can actually succeed (token EIP-712 domain, payTo), and adds its 30-day uptime from our monitor of paid Bazaar listings, how many distinct buyers paid it, and how its price compares with similar listings, with cheaper well-used alternatives. Returns a verdict (ok, caution, avoid) with the reasons.
