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.\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 inline via the X-PAYMENT header using the x402 \"exact\" scheme, settling to the wallet 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. The endpoint returns application/json and has a maximum payment timeout of 300 seconds.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the `/paypal/payments/7` endpoint actually does or what parameters it accepts. The endpoint name suggests PayPal payment processing, but this cannot be confirmed from available material.","tags":[],"capabilities":["x402-payment","pay-per-call","usdc-settlement","base-network","post-endpoint","json-response"],"categories":["finance","payments"],"synonyms":["paypal payments api","x402 paypal","micropayment api","pay-per-request api","lowpaymentfee","base usdc api","crypto payment gateway"],"warnings":["No documentation available — all doc/pricing/API/README pages render only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; impossible to know what parameters the endpoint accepts","The endpoint path references 'paypal/payments' but there is no confirmation of actual PayPal integration","No terms of service, privacy policy, or compliance information visible for a payments-related endpoint"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/7","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/7","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 ($0.02 USDC on Base), but there is zero documentation on what the endpoint actually does, what request body it expects, or what it returns.
