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 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 (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 \"exact\" scheme with no API keys or rate limits required — callers simply attach an X-PAYMENT header with a valid payment proof. The payment timeout is 300 seconds.\n\nThe platform's landing page advertises uniform $0.02 pricing across all endpoints, instant access, and no minimums or commitments. However, documentation is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no examples of what this particular PayPal payments endpoint actually returns or what input it expects. The endpoint name suggests PayPal payment processing functionality, but without documentation this is speculative.","tags":[],"capabilities":["x402-payment-gated","usdc-settlement","base-network","pay-per-call","paypal-payments","no-api-key","no-rate-limit"],"categories":["finance","payments"],"synonyms":["paypal api","payment processing","x402 paypal","lowpaymentfee","micropayment api","usdc payment endpoint","base network api"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all render only 'Connect wallet'","No OpenAPI or schema describing request/response format for this endpoint","The actual functionality of /api/v1/paypal/payments/95 is unknown; 'Premium API Access' is a generic label","No examples of successful responses are available anywhere in the crawl"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/95","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/95","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 402 x402 challenge) and pricing is clear at $0.02/request in USDC on Base.
