Every agent-payable API.

Fresh reliability evaluation for public x402 services. Checks HTTPS reachability, unpaid HTTP 402 behavior, PAYMENT-REQUIRED decoding, discovery metadata, schemas, and quote consistency. Returns a deterministic scored report and public report URL. No account or API key; exact USDC payment on Base.

Who actually pays you, and what else do they buy? We build the payer-to-service map across the whole Bazaar catalog from on-chain settlement, so we can tell you how many distinct agents paid you, how often each returns, and what share of your buyers also pay other x402 services. Pass ?domain=<yours>; omit for the market-wide buyer pool. Individual buyer addresses are never disclosed.

Independent second opinion on an x402 resource. Compares what a seller declares publicly (Bazaar catalogue entry, its own x402 manifest) against what an independent observer sees live right now: price, payTo, network, method and paywall presence. Returns field-level evidence with source, timestamp and hash, a classification per difference, and a signed receipt. Distinguishes protocol-legal dynamic behaviour from real drift.

Batch version of the x402 evidence cross-check, for indexers and routers: up to 25 targets in one call. Each target returns the same field-level evidence, classification and confidence as the single-target resource. One failing target never invalidates the rest of the batch. Never pays any target and never signs an outgoing transaction.
