The specific resource `/api/v1/orders/40/status` returns order status data in JSON format when a valid x402 payment header is included. Payment is settled in USDC on the Base network.\n\nThe endpoint charges a maximum of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The provider's site advertises a flat $0.02/request pricing model across all their APIs with no API keys, no rate limits, and instant access. The x402 challenge uses the \"exact\" payment scheme with a 300-second timeout.\n\nThe broader lowpaymentfee.com platform offers multiple API categories including Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure utilities (geocoding, validation, conversion, generation). All endpoints appear to follow the same $0.02/request pricing. However, this specific listing is for the order status endpoint only, and no detailed documentation about request/response schemas was found in the crawl.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","order-status","pay-per-request","json-response"],"categories":["commerce","data"],"synonyms":["order tracking","order status API","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee"],"warnings":["No request or response schema available — input/output formats are unknown","The endpoint path includes a hardcoded order ID (/orders/40/status); unclear if this generalizes to other order IDs","Documentation pages (/docs, /api, /pricing, /README) returned no meaningful content beyond 'Connect wallet'","The nature of the 'order' being tracked is unspecified — could be a demo or placeholder"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/40/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/40/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 402 challenge, confirming it works.
