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 (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-call upon valid 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. However, documentation pages (docs, pricing, README) all render only a \"Connect wallet\" prompt with no substantive content, so the actual request/response schemas for this PayPal payments endpoint are unknown. The endpoint name suggests PayPal payment processing or data retrieval, but without documentation or example payloads, the exact functionality cannot be confirmed.","tags":[],"capabilities":["x402-payment-gated","pay-per-call","usdc-base","paypal-payments","json-api","no-api-key","post-method"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","crypto-gated paypal","lowpaymentfee paypal","base network payment api","micropayment paypal endpoint"],"warnings":["No documentation available — all doc pages render only 'Connect wallet' with no content","Request and response schemas are completely unknown; the endpoint's actual behavior cannot be verified","The endpoint path suggests PayPal payment functionality but this is unconfirmed","The '/22' path segment suggests a hardcoded resource ID; unclear if this is parameterizable"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/22","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/22","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 with clear pricing ($0.02 USDC on Base).
