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 charges up to 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-payment scheme with no API keys or rate limits required — callers simply attach an `X-PAYMENT` header with a valid payment proof. The endpoint returns `application/json` responses and has a payment timeout of 300 seconds.\n\nThe platform advertises a uniform $0.02/request pricing model across all its endpoints with no minimums or commitments. However, documentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what the `/paypal/payments/77` endpoint actually does or what parameters it accepts. The endpoint is live (returns a valid 402 challenge), but without documentation it is unclear what payload to send or what response to expect.","tags":[],"capabilities":["x402-payment","pay-per-call","usdc-base","post-endpoint","json-response","no-api-key"],"categories":["finance","payments"],"synonyms":["paypal payments api","x402 paypal","crypto-gated api","micropayment api","base network api","lowpaymentfee","pay-per-request api"],"warnings":["No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no technical content","No OpenAPI or request/response schema provided; it is unknown what request body the endpoint expects","The purpose of '/api/v1/paypal/payments/77' is unclear — the name suggests PayPal integration but no details are available","The platform lists many endpoints but none have documented behavior or schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/paypal/payments/77","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/77","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payments.
