}Free, read-only linter for the unpaid path of an x402 endpoint. Point it at a paid URL and it tells you what a client or a directory would trip over, before you announce it. It never pays and never signs, so it cannot test settlement.

Unpaid lint of an x402 endpoint: fetches the 402 (GET and POST), then checks the challenge (version, accepts[] fields, CAIP-2 network, payTo/asset/amount sanity, EIP-712 name/version, timeouts, resource), transport (redirects, cache headers, CORS) and discovery files. Returns findings with ids, severities and fixes. Never pays. Free.
url必填methodLint an x402 endpoint's unpaid 402 and report, per directory, whether it meets what x402dash (unpaid GET must return 402), x402scan (OpenAPI x-payment-info or /.well-known/x402, input schema), the402 (validator 'payable') and the CDP/PayAI Bazaar (bazaar extension, description <= 500 chars, non-tunnel https host; listing then needs one settled payment) were known to check. Never pays. Free.
url必填methodLint a PaymentRequired object you already have (decoded JSON, a JSON string, or the raw base64 PAYMENT-REQUIRED header). Same field/value checks as lint_x402_endpoint, no network access. Free.
