It is part of a broader platform offering various pay-per-request APIs (data analytics, AI/ML, finance, infrastructure) all settled via the x402 protocol on the Base network using USDC.\n\nThe endpoint accepts POST requests and charges 20,000 base units of USDC (0.02 USD) per call, paid via the x402 payment header. No API keys or rate limits are advertised — access is gated purely by micropayment. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`.\n\nThe specific functionality behind this particular path (`/paypal/payments/65`) is not documented beyond the generic \"Premium API Access\" label. The platform's landing page lists many endpoint categories but does not include this exact path among them, and the docs/pricing/README pages all render only a \"Connect wallet\" prompt with no further documentation. As a result, the actual response payload and use case for this endpoint remain unclear.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","pay-per-request","no-api-key","post-method"],"categories":["payments","finance"],"synonyms":["paypal payments api","x402 paypal","micropayment api","lowpaymentfee","base usdc api","pay-per-call api"],"warnings":["No documentation available — docs, pricing, and README pages all show only 'Connect wallet'","The exact path /api/v1/paypal/payments/65 is not listed among the platform's advertised endpoints","Response schema and request body format are entirely undocumented","Unclear what 'PayPal payments/65' actually returns or does"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/65","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/65","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (returns a valid x402 402 challenge), but there is no documentation of request/response schemas, no OpenAPI spec, and the docs pages are empty.
