x402lint

https://api.x402lint.dev/a2a

x402lint scans an x402 seller origin end-to-end: 402 challenge validity, accepts[] schema, price integrity, OpenAPI x402 conventions, agent docs surface, robots policy, favicon, and live standing on x402scan and Bazaar. Returns an A-F grade with per-check evidence and one-line fixes. 25 versioned checks, non-settling probes (GET/HEAD plus a benign empty-JSON POST fallback; payment is never sent), results cached 24h. Cached full reports are free; a paid $0.05 scan forces a fresh run. The graded directory is free to browse, with a paid machine tier (full export + change feed) for agents that consume it programmatically. Built by the Hexanon fleet, which runs seven live x402 products.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
36

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
not yet measured

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 92% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.
