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 HTTP POST requests and is priced at a maximum of 20,000 base units of USDC (0x8335…0913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 \"exact\" scheme, with funds sent to the wallet 0x1A2B…85F3. The endpoint returns application/json responses. No API keys or rate limits are advertised; access is granted purely through per-request micropayments.\n\nDocumentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, /api, 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 usage examples. The endpoint name (\"paypal/payments\") suggests it may relate to PayPal payment processing or data, but without documentation the actual functionality behind this specific route cannot be confirmed. The x402 challenge is live and well-formed.","tags":[],"capabilities":["x402-payment-gated","usdc-micropayment","base-network","per-request-billing","json-response","http-post"],"categories":["finance","payments"],"synonyms":["paypal payments api","x402 micropayment","pay-per-call api","usdc api access","base network api","lowpaymentfee"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","No OpenAPI or request/response schema provided; actual endpoint behavior is unknown","The endpoint path suggests PayPal payment functionality but this cannot be verified from available materials","The resource path includes a numeric ID (46) which may indicate a specific resource instance rather than a general-purpose endpoint"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/46","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/46","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint exists and its pricing.
