The specific resource `/api/v1/orders/94/status` returns order status data for order ID 94 in JSON format, gated behind a per-request USDC micropayment on the Base network.\n\nThe endpoint accepts POST requests and requires an X-PAYMENT header conforming to x402 version 1. The maximum amount required per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimal places. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.\n\nlowpaymentfee.com hosts a broader suite of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. No API keys, rate limits, or commitments are required. However, the crawled documentation pages (docs, pricing, README) returned only a \"Connect wallet\" prompt with no substantive content, so the actual response schema and detailed behavior of this specific order-status endpoint remain undocumented.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status API","x402 endpoint","micropayment API","USDC pay-per-call","lowpaymentfee","Base USDC API"],"warnings":["No API documentation available — docs, pricing, and README pages all return only a 'Connect wallet' prompt.","No response schema or example response is provided; actual output format is unknown.","The endpoint path is hardcoded to order ID 94; it is unclear whether other order IDs are supported or how to discover them.","The broader site advertises many API categories (AI, finance, analytics, etc.) but none could be verified beyond their listing on the homepage."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/94/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/94/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint exists and its pricing ($0.02 USDC on Base).
