It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML inference, finance, crypto, and utility services — all gated by 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…0913 on Base, 6 decimals), which equals $0.02 per request. Payment is made via the x402 \"exact\" scheme, meaning the caller includes an X-PAYMENT header with a signed payment to the provider's address (0x1A2B…85F3). No API keys or accounts are required; access is granted immediately upon valid payment. The platform advertises no rate limits and no minimum commitments.\n\nDocumentation 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/86` endpoint actually returns or what input it expects beyond being a POST endpoint with JSON output. The endpoint name suggests PayPal payment processing functionality, but this cannot be confirmed from available materials. Prospective users should test the endpoint directly to understand its behavior.","tags":[],"capabilities":["x402-payment-gated","usdc-settlement","base-network","pay-per-call","no-api-key","post-endpoint","json-response"],"categories":["finance","payments"],"synonyms":["paypal payments api","x402 paypal","micropayment api","pay-per-call payments","lowpaymentfee","usdc api access","base network api"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; endpoint behavior is unknown beyond the URL path name","The actual functionality of /api/v1/paypal/payments/86 is unverified — the name suggests PayPal integration but this cannot be confirmed","No rate limit or uptime guarantees documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/86","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/86","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (returns a valid x402 402 challenge), and pricing is clear at $0.02/request in USDC on Base.
