Cheap connectivity-check endpoint. Verifies the full x402 settlement path (signature -> CDP facilitator -> on-chain transferWithAuthorization) for $0.01 so AI agents can validate wallet + network + facilitator wiring before committing to higher-value AML calls.

Find better alternatives to an x402 endpoint. Given a resource URL, returns the top semantically-similar endpoints (matched on advertised purpose via description embeddings) that currently OUT-SCORE it on our deterministic trust score — so an agent about to pay a mediocre endpoint can discover a more reliable, better-settled one serving the same function. Each result carries its trust score, grade, cosine similarity, advertised price and free endpoint-page URL. The price fields stay machine-readable: amountUsd is always the raw advertised amount, and the separate boolean priceCeiling is true when the endpoint uses the x402 'upto' scheme, i.e. amountUsd is an authorization ceiling and the real charge is typically lower. Same-host siblings and 'avoid'-flagged endpoints are excluded. Returns an empty list (still a valid answer) when nothing beats the subject.

Verify any third-party x402 endpoint is alive and correctly configured before paying it: a bounded GET/402 preflight fetches the payment contract, checks reachability and response latency, validates accepts, network, price and expiry against the x402 spec, and returns a signed observation receipt with an observed_at timestamp you can cite — protection against ghost endpoints, dead quotes and wasted USDC. Limitation: no payment is made, one endpoint per call, and a passing probe proves the contr…

Verify an x402 purchase actually settled and delivered what you paid for: submit bounded, non-secret metadata for the payment requirement, payment response, delivery receipt and settlement reference, and receive a single deterministic verdict — proven, conflicting, or missing — field by field, suitable to attach to a refund request or dispute. Limitation: verdicts are computed from the artifacts you provide; we do not fetch chain state or contact the provider on your behalf.

Turn an OpenAPI document into a compact operation index for planning and tool selection. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
