It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific resource `/api/v1/orders/179/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 by including an X-PAYMENT header; no API keys or accounts are required. The timeout for payment settlement is 300 seconds.\n\nThe platform advertises no rate limits, no API keys, no minimums, and instant access. Documentation pages (/docs, /pricing, /api, /README) all resolve but contain only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no example payloads. The endpoint is live — it returned a proper 402 challenge on probe.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC payment API","pay-per-call API","Base network API","lowpaymentfee"],"warnings":["Endpoint is hardcoded to order 179 — unclear if other order IDs are queryable or if this is a demo/placeholder.","All documentation pages (/docs, /pricing, /api, /README) return only 'Connect wallet' with no technical content.","No OpenAPI spec or response schema available — response format is unknown.","No request body schema documented; unclear what (if any) POST body is expected."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/179/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/179/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, but the resource is narrowly scoped to a single hardcoded order ID.
