It is part of a broader platform that offers dozens of x402-protocol pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per call, settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/paypal/payments/97` sits under what appears to be a PayPal payments category. The x402 challenge confirms it is live, accepting POST requests, and requires a payment of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02) per call. Payment is made via the x402 \"exact\" scheme to wallet 0x1A2B…85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.\n\nDocumentation on the site is extremely thin — the docs, API, pricing, 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 description of what the PayPal payments endpoint actually returns or what parameters it accepts. The endpoint is confirmed live via the 402 challenge, but its actual functionality and output format remain unknown.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","paypal-payments","no-api-key","no-rate-limit"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","lowpaymentfee","usdc micropayment","base network api","pay-per-call api","crypto payment endpoint"],"warnings":["No documentation available — all doc pages render only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; input parameters and output format are completely unknown","The purpose of '/api/v1/paypal/payments/97' is unclear — it may relate to PayPal payment processing but this is inferred solely from the URL path","The trailing '97' in the path suggests a resource ID, meaning this may be a specific payment record rather than a general-purpose endpoint"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/97","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/97","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
