It is part of a broader platform that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all settled via USDC on the Base network with no API keys or rate limits required.\n\nThe specific endpoint `/api/v1/stripe/invoices/194` accepts POST requests and returns JSON. The x402 challenge confirms it is live, requesting up to 0.02 USDC (20,000 base units of USDC with 6 decimals) per call, paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract on Base (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The payment scheme is \"exact\" with a 300-second timeout.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what data this invoice endpoint actually returns or what parameters it accepts. The platform's landing page lists many endpoints at $0.02 each but provides no technical details beyond endpoint paths and short labels. Without documentation, the actual functionality and response format of this specific endpoint remain unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-invoice-access","pay-per-request","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe invoice API","x402 paid API","USDC micropayment API","Base network API","pay-per-call invoice","lowpaymentfee"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; input parameters and output format are unknown","The purpose of accessing a specific Stripe invoice (#194) via a public paid endpoint is unclear","Cannot verify what data is actually returned without making a paid request"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/invoices/194","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/invoices/194","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or what the endpoint actually returns.
