Tools (3)

`check_directory_readiness`	Lint 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.
`lint_payment_required`	Lint 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.
`lint_x402_endpoint`	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.
