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 specific endpoint probed (/api/v1/stripe/customers/128) costs $0.02 per request (20,000 base units of USDC with 6 decimals). The broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing across a wide catalog of APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and infrastructure utilities. All endpoints are x402-gated — no API keys, no rate limits, and no sign-up required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nDocumentation is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual behavior of this particular Stripe customers endpoint — what data it returns, what POST body it expects — is unknown from the available material. The endpoint is confirmed live (returns a well-formed 402 challenge).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-customer-data","per-call-pricing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stripe customer API","x402 paid API","USDC micropayment API","pay-per-call API","Base network API","lowpaymentfee","crypto payment endpoint"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all show only 'Connect wallet'","No OpenAPI or schema definition; request body and response format are completely unknown","Endpoint exposes what appears to be Stripe customer data — unclear data provenance and potential privacy/compliance concerns","The specific resource path (/stripe/customers/128) suggests a single hardcoded customer record, which is unusual"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/128","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/128","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schemas, no examples.
