It is part of a broader platform that offers 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 and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/85/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 X-PAYMENT header per the x402 protocol. No API keys, rate limits, or upfront commitments are required — callers simply attach a valid payment proof to each request.\n\nThe platform's landing page advertises categories including metrics, reports, data export, insights, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation endpoints. However, this specific listing covers only the order status endpoint. Documentation pages (/docs, /api, /pricing, /README) appear to require wallet connection and did not yield substantive content during crawl, so detailed request/response schemas are unavailable.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC payment API","Base network API","pay-per-call"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) returned no useful content — all gated behind wallet connection.","The endpoint path is hardcoded to order ID 85; it is unclear whether other order IDs are supported or how to discover them.","No request body schema or response schema is documented anywhere in the crawled material.","The 'Premium API Access' description is generic and does not clarify what data is returned."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/85/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/85/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 (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
