It is part of a broader platform that offers dozens of pay-per-call API endpoints across categories including data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/199/status` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers must include an X-PAYMENT header with a valid payment proof. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show a \"Connect wallet\" prompt), so the actual response schema and behavior of this endpoint are not documented. It is unclear whether this is a demo/placeholder endpoint or a production service. The order ID (199) is hardcoded in the URL, suggesting this may be a specific resource lookup rather than a general-purpose API.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","json-response","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","pay-per-request API","USDC payment API","Base network API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) are all empty beyond a 'Connect wallet' prompt","No response schema or example responses available","Endpoint URL contains a hardcoded order ID (199); unclear if other order IDs are supported","Platform appears to be a demo or early-stage project with minimal documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/199/status","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/orders/199/status","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, but documentation is effectively nonexistent — all pages beyond the landing page show only 'Connect wallet'.
