The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 \"exact\" scheme.\n\nThe hosting site lowpaymentfee.com advertises a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the x402 challenge for this specific endpoint advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site's stated pricing.\n\nDocumentation is extremely sparse. The /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no explanation of what the Stripe customers endpoint actually returns or what input it expects. The endpoint is confirmed live (402 challenge captured), but the actual functionality and data returned remain unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-customer-data","per-call-pricing","no-api-key"],"categories":["finance","data"],"synonyms":["stripe customer API","x402 paid API","USDC micropayment API","pay-per-call API","Base network API","lowpaymentfee"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return only a wallet connect prompt","No OpenAPI or request/response schema provided; actual endpoint behavior is unknown","Purpose of exposing a single Stripe customer record (ID 149) via public paywall is unclear","No information on data freshness, uptime guarantees, or rate limits beyond marketing claims"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/149","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/149","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 OpenAPI spec, no request/response examples, and no explanation of what data is actually returned.
