It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML, 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-request upon payment. The platform's landing page confirms a flat $0.02/request pricing model across all listed endpoints.\n\nDocumentation is extremely sparse. The /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the PayPal payments endpoint actually returns or what input it expects. The endpoint name suggests it may proxy or interact with PayPal payment data, but this is speculative — the actual functionality behind this endpoint is unclear from available materials.","tags":[],"capabilities":["x402-payment-gated","pay-per-request","usdc-settlement","base-network","paypal-payments","post-method","no-api-key-required"],"categories":["finance","payments"],"synonyms":["paypal api","payment processing","x402 paypal","crypto-gated api","lowpaymentfee","pay-per-call payments","usdc api access"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response format","The actual functionality of /api/v1/paypal/payments/74 is unknown — 'Premium API Access' is generic","No examples of successful responses are available","The platform lists many endpoints but none appear to have public documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/74","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/74","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 402 challenge with clear pricing.
