It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML, finance, and infrastructure utilities — all gated by 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 (contract `0x8335…2913` on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 \"exact\" scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted per-call upon valid payment. The platform's landing page confirms a flat $0.02/request pricing model across all listed endpoints.\n\nDocumentation is extremely sparse. The docs, API, 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 it may relate to PayPal payment processing or data retrieval, but this cannot be confirmed from available materials. Prospective users should exercise caution given the lack of documentation about the endpoint's actual functionality.","tags":[],"capabilities":["x402-payment","pay-per-call","usdc-base","paypal-payments","post-endpoint","no-api-key"],"categories":["finance","payments"],"synonyms":["paypal api","payment processing","x402 paypal","lowpaymentfee","base usdc api","micropayment api","pay per call api"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response format","Actual functionality of /api/v1/paypal/payments/39 is unknown — the endpoint name suggests PayPal payment operations but nothing confirms this","No examples of successful responses available","Platform lists many endpoints but none appear to have public documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/39","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/39","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing.
