It is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request, settled in USDC on the Base network.\n\nThe x402 challenge confirms the endpoint is live and accepts POST requests. Payment is made via the x402 \"exact\" scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a max amount of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02. The response MIME type is `application/json`. No API keys or rate limits are advertised; access is gated purely by the per-request micropayment.\n\nDocumentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the `/api/v1/stripe/customers/15` endpoint actually returns or what input it expects. The endpoint path suggests it retrieves or manipulates a Stripe customer record (ID 15), but the exact functionality is unverified. The platform lists many other endpoints (analytics, AI, finance, utilities) at the same price point, but none have documented schemas either.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-customer-api","json-response","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe customer API","x402 micropayment API","USDC pay-per-call","lowpaymentfee","Base network API","crypto-gated API","402 payment endpoint"],"warnings":["No OpenAPI schema or request/response documentation available","All documentation pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no useful content","The specific functionality of /api/v1/stripe/customers/15 is undocumented — it is unclear what data it returns or what POST body it expects","The endpoint references a hardcoded Stripe customer ID (15), which may be a demo or placeholder"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/15","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/15","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the purpose of this specific Stripe customer endpoint is unclear.
