The specific resource `/api/v1/stripe/customers/35` appears to be part of a broader platform offering dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints on the platform are priced at $0.02 per request, settled in USDC on the Base network with no API keys, rate limits, or commitments required.\n\nThe probed endpoint returns a valid x402 challenge (HTTP 402) advertising a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the \"exact\" scheme to the specified payTo address. The endpoint accepts POST requests and returns application/json. However, the specific functionality of this particular `/stripe/customers/35` route is unclear — it is not listed among the publicly advertised APIs on the landing page, and may relate to Stripe customer management or a demo/test resource.\n\nDocumentation is extremely thin: the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no examples of what this endpoint actually returns. The platform's landing page confirms the pricing model and lists other available endpoints, but provides no detail on request parameters or response formats for any of them.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-customers","json-response","no-api-key"],"categories":["payments","infrastructure"],"synonyms":["x402 API","USDC pay-per-call","Base network API","lowpaymentfee","stripe customer API","micropayment API","crypto-gated endpoint"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all return only a wallet-connect prompt","This specific endpoint (/api/v1/stripe/customers/35) is not listed among the platform's advertised APIs; its purpose is unclear","No OpenAPI spec or request/response schema provided","No examples of successful responses available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/35","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/stripe/customers/35","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
