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 via 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, 6 decimals), which equals $0.02 per call. Payment is made via the x402 \"exact\" scheme, settling to the wallet address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. There are no API keys, no rate limits, and no subscriptions — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe exact functionality behind this particular path (`/paypal/payments/49`) is not documented in the crawled material. The endpoint name suggests it relates to PayPal payment processing or data, but no request/response schema, parameter documentation, or usage examples were found. The platform's docs, pricing, and API pages all rendered only a \"Connect wallet\" prompt with no additional content. Prospective users should test the endpoint or contact the provider for details on what data or action this specific resource returns.","tags":[],"capabilities":["x402-payment-gated","pay-per-request","base-network","usdc-settlement","no-api-key","post-method","paypal-payments"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","pay-per-call payment endpoint","lowpaymentfee","base usdc api","micropayment api","paypal integration"],"warnings":["No documentation found for what /api/v1/paypal/payments/49 actually returns or accepts as input","All doc pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no content","The endpoint name suggests PayPal payment functionality but this is unverified","No OpenAPI spec, no request/response schema, and no usage examples available","The specific resource ID '49' in the path is unexplained"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/49","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/49","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).
