It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.\n\nThe x402 challenge confirms the endpoint is live and accepts exact-scheme payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum amount required is 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The timeout for payment settlement is 300 seconds.\n\nThe specific endpoint probed (/api/v1/orders/19/status) appears to be an order-status lookup, but the platform's landing page does not list this particular route among its advertised APIs. The advertised categories include metrics, reports, data export, insights, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation — all at the same $0.02 price point. Documentation pages (docs, pricing, README) returned only a \"Connect wallet\" prompt with no substantive content, so details about request/response schemas, authentication flows, and actual data returned are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment API","USDC pay-per-call","Base network API","lowpaymentfee","402 payment required API","crypto-gated endpoint"],"warnings":["No documentation available — all doc pages return only 'Connect wallet' with no content","No request or response schema provided; actual data returned is unknown","The specific endpoint /api/v1/orders/19/status is not listed among the platform's advertised APIs — it may be a demo or test route","The endpoint is hardcoded to order ID 19; unclear if other order IDs are supported or how to discover them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/19/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/19/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, and the specific order-status endpoint is not listed among the platform's advertised APIs.
