AlicenseAqualityDmaintenanceEnables AI agents to scan payment endpoints for safety, returning a letter grade (A–F) and verdict before authorizing payments.241 npmMIT- AlicenseNot gradedqualityBmaintenanceEnables agents and IDE assistants to validate x402 payment endpoints without shelling out: it fetches a URL unpaid and returns a conformance report on the returned 402 challenge, decodes and classifies base64 payment blobs, and summarises which scheme/network pairs a facilitator can settle.MIT
- FlicenseNot gradedqualityBmaintenanceEnables autonomous agents to inspect and audit unfamiliar x402 endpoints before spending USDC, using bounded read-only probes to surface payment challenges, pricing, network, receiver, and operational signals without signing or spending funds.-
- AlicenseAqualityCmaintenanceEnables agents to perform a paid trust and liveness audit on any x402 resource URL, returning a verdict, trust score, deductions, terms, schema quality, catalog presence, and diff against the previous check.1MIT
- FlicenseNot gradedqualityAmaintenanceEnables AI agents to search and verify machine-payable HTTP 402/x402 APIs using live probe data, providing ranked results by liveness, uptime, price, and trustworthiness.-

Scored across 3 tools
Each tool occupies a clearly separate slot: one endpoint probe (scan_endpoint), a sequential driver over up to 10 URLs (scan_batch), and a catalog-stats fetcher (census_stats). The overlap between scan_endpoint and scan_batch is explicit and documented, so an agent can pick correctly without guessing. No two tools could plausibly be swapped for the same intent.
All names are snake_case and readable, with scan_endpoint/scan_batch forming a clean verb_noun pair. census_stats breaks the verb-first pattern by being noun-only, a minor but noticeable deviation from an otherwise tight convention.
Three tools is a small but defensible surface for a focused endpoint scanner, and each has a distinct job. census_stats is somewhat tangential (static blog numbers plus a best-effort catalog fetch), which makes the set feel slightly padded at the edges even though nothing is redundant.
The core lifecycle is covered: single probe, batched probe with per-item error isolation, and catalog context, all with a defined A/B/C/F grade and documented safety guards. Gaps are minor — there is no way to inspect or validate a PAYMENT-REQUIRED envelope in isolation, and no persistence/export of prior scan results for the batch case.
