It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated via the x402 payment protocol on the Base network.\n\nThe specific endpoint accepts HTTP 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 inline via the X-PAYMENT header; no API keys or accounts are required. The x402 challenge confirms the endpoint is live, returning a proper 402 with version 1 of the protocol and a 300-second payment timeout.\n\nDocumentation is extremely sparse. The landing page lists available endpoints and pricing but the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no explanation of what the PayPal payments endpoint actually returns or what input it expects. The endpoint's purpose — whether it initiates a PayPal payment, retrieves payment details, or something else — cannot be determined from the available material.","tags":[],"capabilities":["x402-payment-gated","pay-per-call","base-network","usdc-settlement","paypal-payments","http-post"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","lowpaymentfee","pay-per-request api","micropayment api","base usdc api","402 payment endpoint"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all render only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; input format and output structure are unknown","The purpose of /api/v1/paypal/payments/47 is unclear — it is not explained anywhere on the site","The platform lists many endpoints but none appear to have technical documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/47","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/47","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear at $0.02/request in USDC on Base.
