It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML inference, finance, and infrastructure utilities — all gated by the x402 payment protocol on the Base network.\n\nThe specific endpoint accepts POST requests and is priced at 20,000 base units of USDC (contract `0x8335…2913` on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 exact-payment scheme by including an `X-PAYMENT` header. No API keys or rate limits are advertised; access is instant once payment is attached. The payment timeout is 300 seconds.\n\nThe platform's landing page lists a uniform $0.02/request pricing model across all endpoints with no minimums or commitments. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the `/paypal/payments/69` endpoint actually returns or what input it expects beyond a POST body. The endpoint name suggests PayPal payment processing, but without documentation this is speculative.","tags":[],"capabilities":["x402-payment","pay-per-call","usdc-base","paypal-payments","no-api-key","post-endpoint"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","crypto-gated payment endpoint","lowpaymentfee","base usdc api","pay-per-request api","micropayment api"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or output schema provided; request and response formats are completely unknown.","The endpoint path suggests PayPal payment functionality, but this is unconfirmed — no description of actual behavior exists.","The platform lists many endpoints across diverse categories (AI, finance, geocoding, etc.) all at $0.02 — unclear if these are functional or placeholder."],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/69","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/paypal/payments/69","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (returns a valid x402 402 challenge) and pricing is clear ($0.02 USDC on Base).
