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 a maximum of 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 funds sent to the address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.\n\nDocumentation is extremely sparse. The landing page lists available endpoints and pricing but the /docs, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further 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 PayPal-related payment processing or data, but the exact functionality cannot be confirmed from available materials.","tags":[],"capabilities":["x402-payment-gated","usdc-settlement","base-network","pay-per-call","paypal-payments","no-api-key","post-method"],"categories":["finance","payments"],"synonyms":["paypal payment api","x402 paypal","crypto-gated paypal","low fee payment api","usdc pay-per-call","base network api","micropayment api"],"warnings":["No documentation available — /docs, /pricing, and /README pages all show only 'Connect wallet' with no content","No OpenAPI spec or request/response schema provided","Exact functionality of /api/v1/paypal/payments/72 is unknown — the name suggests PayPal payment processing but this cannot be verified","No examples of expected input or output"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/72","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/72","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, no request/response schemas, no examples, and all doc pages render only 'Connect wallet'.
