It is settled on the Base network using USDC (contract 0x8335…2913) with a per-request cost of $0.02 (20,000 base units at 6 decimals). The endpoint accepts POST requests and returns application/json responses.\n\nThe broader lowpaymentfee.com platform advertises a suite of x402-gated APIs spanning data & analytics (metrics, reports, data export, insights), AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and instant access.\n\nHowever, the specific endpoint being listed here (/api/v1/stripe/invoices/188) does not appear in the platform's published API catalog. Its purpose — accessing a particular Stripe invoice — is unclear: it may return invoice details, trigger an invoice action, or serve as a demo endpoint. No request body schema, response schema, or documentation beyond the x402 challenge is available. The docs, pricing, API, and README pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-invoice","post-endpoint","json-response","pay-per-request"],"categories":["finance","infrastructure"],"synonyms":["stripe invoice API","x402 paid endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee","402 payment protocol"],"warnings":["Endpoint /api/v1/stripe/invoices/188 is not listed in the platform's own API catalog — purpose is unclear","No request body schema or response schema available","All documentation pages (docs, pricing, API, README) returned only 'Connect wallet' with no substantive content","No OpenAPI spec or ai-plugin manifest found","The endpoint references a specific Stripe invoice ID (188) which may be ephemeral or a demo resource"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/invoices/188","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/188","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 captured) and pricing is clear ($0.02 USDC on Base), but there is no request/response schema, no documentation, and the specific invoice endpoint is not listed in the platform's own catalog.
