It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract `0x8335…2913`) via the x402 \"exact\" scheme. The maximum amount required per call is 20,000 base units of USDC, which at 6 decimals equals $0.02 USD.\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (`/stripe/customers/197`) is not featured in the site's public catalog; it appears to be a Stripe customer record lookup rather than one of the advertised general-purpose APIs.\n\nDocumentation is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's `outputSchema` stub, and no examples of what the endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the actual data payload and required POST body are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","stripe-customer-data","pay-per-call","no-api-key"],"categories":["finance","data"],"synonyms":["stripe customer lookup","x402 API","USDC micropayment API","pay-per-request API","Base network API","crypto-paid API"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","No OpenAPI spec or request/response schema provided","This specific endpoint (/stripe/customers/197) is not listed in the site's public API catalog","Unknown what POST body is expected or what data is returned","Exposing Stripe customer data via a public pay-per-call endpoint raises data privacy concerns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/197","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/197","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 USDC on Base), but there is no documentation, no request/response schema, no examples, and the specific endpoint (/stripe/customers/197) is not listed in the site's own catalog.
