It is part of a broader platform that offers a variety of pay-per-call APIs spanning 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/64/status` is labeled \"Premium API Access\" in the x402 challenge. The payment scheme is \"exact\" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 protocol's X-PAYMENT header; no API keys or accounts are needed. The endpoint accepts POST requests and returns application/json.\n\nThe broader platform advertises no rate limits, no API keys, no minimums, and instant access. However, documentation pages (/docs, /pricing, /api, /README) all returned only a \"Connect wallet\" prompt with no substantive content, so the actual response schema for this order-status endpoint is unknown. There is no OpenAPI spec, no example responses, and no detailed documentation available from the crawl. The endpoint is confirmed live (402 challenge returned successfully).","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","order tracking","lowpaymentfee"],"warnings":["Endpoint path is hardcoded to order ID 64 — unclear if other order IDs are supported or how to discover them.","No documentation available: /docs, /pricing, /api, and /README all returned only 'Connect wallet' with no content.","No OpenAPI spec or response schema provided — response format is unknown.","The 'Premium API Access' label is generic and does not describe what data is actually returned."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/64/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/64/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
