It is part of a broader platform offering various pay-per-request APIs settled via the x402 protocol on the Base network using USDC. Each call costs $0.02 (20,000 base units of USDC with 6 decimals).\n\nThe platform advertises itself as requiring no API keys, no rate limits, and no commitments — users pay per request using an x402 payment header. The specific functionality of this particular endpoint (`/paypal/payments/82`) is not documented beyond the generic \"Premium API Access\" label. It accepts POST requests and returns `application/json`. The broader site lists categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities, all at the same $0.02 price point.\n\nThe endpoint is live and returns a valid x402 challenge (HTTP 402) with payment details specifying USDC on Base (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The payment recipient is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout. Documentation beyond the landing page is essentially empty (all sub-pages just show \"Connect wallet\"), so the actual request/response schema for this endpoint is unknown.","tags":[],"capabilities":["x402-payment","usdc-base-settlement","pay-per-request","json-response","post-method"],"categories":["finance","payments"],"synonyms":["paypal payments api","x402 paypal","low fee payment api","crypto payment endpoint","base network api","usdc api access","pay-per-call api"],"warnings":["No documentation available — all doc/pricing/README pages show only 'Connect wallet'","The specific functionality of /api/v1/paypal/payments/82 is undocumented; 'Premium API Access' is generic","No request or response schema provided","The endpoint path suggests PayPal integration but no details confirm what it actually does"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/82","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/82","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (valid 402 challenge), but there is no documentation of request/response schemas, no examples, and the purpose of this specific endpoint (/paypal/payments/82) is unclear.
