The provider operates a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC via the x402 protocol.\n\nThe specific endpoint probed (`/api/v1/stripe/customers/23`) is described by the provider simply as \"Premium API Access\" and accepts HTTP POST requests. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 per request (USDC uses 6 decimals). This aligns with the provider's advertised flat pricing of $0.02 per request across all endpoints. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation pages (/docs, /pricing, /api, /README) all returned only a \"Connect wallet\" prompt with no substantive content, so the actual behavior, request schema, and response format of this particular endpoint remain undocumented. It is unclear what data or functionality the `/stripe/customers/23` path actually returns — the name suggests Stripe customer data retrieval or manipulation, but no schema or examples are available.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","per-call-pricing","http-post","stripe-customer-data"],"categories":["finance","infrastructure"],"synonyms":["x402 API","pay-per-call API","USDC micropayment","Base network API","Stripe customer endpoint","lowpaymentfee","crypto-paid API"],"warnings":["No API documentation available — all doc pages (/docs, /pricing, /api, /README) return only a wallet-connect prompt","The endpoint path references a specific Stripe customer ID (23), which is unusual for a general-purpose API — purpose is unclear","No request body schema or response schema documented anywhere","No OpenAPI spec or AI plugin manifest found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/23","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/23","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/request in USDC on Base).
