It is part of a broader platform offering multiple pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities—all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/stripe/charges/15` accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The maximum amount required is 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 given USDC's 6 decimals. The platform advertises no API keys, no rate limits, and instant access.\n\nDocumentation is extremely sparse—the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. The actual behavior and response format of this specific endpoint are not documented beyond the generic \"Premium API Access\" label. It is unclear what data or functionality this particular charges endpoint returns.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","stripe-charges"],"categories":["finance","infrastructure"],"synonyms":["x402 API","pay-per-call API","USDC micropayment endpoint","Base network API","crypto payment API","lowpaymentfee","stripe charges API"],"warnings":["No documentation available beyond landing page—docs, API, pricing, and README pages all show only 'Connect wallet'","The specific functionality of /api/v1/stripe/charges/15 is undocumented; 'Premium API Access' is generic","No request body schema or response schema provided","No OpenAPI spec or AI plugin manifest available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/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/charges/15","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation on what the endpoint actually returns, no request/response schema, and the docs pages are empty.
