It is part of a broader platform offering dozens of pay-per-call 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 resource `/api/v1/stripe/charges/191` appears to be a Stripe charges-related endpoint. However, the crawled documentation is extremely thin — every page beyond the landing page returned only a \"Connect wallet\" stub, so there is no detailed schema, parameter documentation, or example responses available. The x402 challenge confirms the endpoint is live: it accepts POST requests, charges a maximum of 20,000 base units of USDC (0.02 USD given 6 decimals) on Base, and pays out to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`.\n\nBecause the endpoint path references \"stripe/charges\" it likely returns or processes Stripe charge data, but without documentation or example responses this is speculative. The platform advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to each request.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-charges","post-method"],"categories":["finance","infrastructure"],"synonyms":["stripe charges API","x402 payment API","USDC micropayment endpoint","low fee API","pay-per-call API","Base network API","crypto-paid API"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet' stub","Endpoint purpose is inferred from URL path only; no schema or response examples exist","No OpenAPI or machine-readable spec provided","The broader platform lists many endpoints but none have documented request/response formats"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/191","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/191","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and confirms pricing and network details, but there is effectively zero documentation: no OpenAPI spec, no parameter descriptions, no example responses.
