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 using USDC.\n\nThe specific endpoint accepts POST requests and is priced at 20,000 base units of USDC (the asset at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, which has 6 decimals), equating to $0.02 per request. Payment is made via the x402 `exact` scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through on-chain micropayment.\n\nThe exact functionality behind the `/api/v1/paypal/payments/26` path is not documented in the crawled material. The endpoint name suggests it relates to PayPal payment processing or data retrieval, but no request/response schema, parameter documentation, or usage examples were found. The platform's docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. Prospective users should test the endpoint with a small payment to determine its actual behavior before relying on it in production.","tags":[],"capabilities":["x402-payment-gated","usdc-base-settlement","pay-per-request","no-api-key","paypal-payments","post-method"],"categories":["payments","finance"],"synonyms":["paypal api","payment processing","x402 paypal","micropayment api","usdc payment endpoint","lowpaymentfee","base network api"],"warnings":["No request or response schema documented — actual endpoint behavior is unknown","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content","The endpoint path '/api/v1/paypal/payments/26' implies PayPal integration but no details confirm this","No OpenAPI spec, no ai-plugin manifest, no agents.txt found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/26","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/26","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), but there is no documentation of what the endpoint actually does, no request/response schema, and no examples.
