It is part of a broader platform offering dozens of pay-per-call API endpoints across categories including data analytics, AI/ML inference, finance/Web3, 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 (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 \"exact\" scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted per-request upon payment. The response MIME type is `application/json`.\n\nThe platform's landing page lists a uniform $0.02/request pricing model across all endpoints with no minimums or commitments. Documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all returned only a \"Connect wallet\" prompt with no further technical detail, so the actual request body schema, response fields, and the specific functionality behind this PayPal payments endpoint remain undocumented. The endpoint name suggests it may relate to PayPal payment processing or data retrieval, but this cannot be confirmed from available materials.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-call","paypal-payments","json-api","no-api-key"],"categories":["finance","payments"],"synonyms":["paypal api","payment processing","x402 paypal","lowpaymentfee","base usdc api","micropayment api","pay-per-request api"],"warnings":["No documentation available — all doc pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no technical content.","The actual functionality of /api/v1/paypal/payments/41 is unknown; the name suggests PayPal payment operations but nothing confirms this.","No request body schema or response schema is documented or inferrable.","The '/41' path segment suggests a hardcoded resource ID; unclear if this is parameterizable."],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/41","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/41","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 402 challenge with clear pricing.
