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 settled in USDC on the Base network.\n\nThe specific resource `/api/v1/orders/185/status` is labeled \"Premium API Access\" in the x402 challenge. The challenge advertises a maxAmountRequired of 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 \"exact\" scheme, with a 300-second timeout. No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid payment proof.\n\nThe platform's landing page lists additional endpoints across four categories: Data & Analytics (metrics, reports, export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure (geocoding, validation, conversion, generation). All are advertised at the same $0.02/request price point. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no further technical detail.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","premium API access","402 payment endpoint"],"warnings":["No OpenAPI or schema documentation available — response format is unknown.","Documentation, pricing, API, and README pages all return only 'Connect wallet' with no content.","The endpoint path contains a hardcoded order ID (185); it is unclear whether this is a demo or a real resource.","No response example could be obtained; example_response_json is null."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/185/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/185/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 captured) and pricing is clear ($0.02 USDC on Base).
