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 advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 6 decimals), which equals $0.02. Payment is sent to 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe specific endpoint `/api/v1/orders/11/status` appears to be a single hardcoded order-status lookup. The platform's landing page lists many other endpoints (metrics, reports, sentiment analysis, summarization, classification, embeddings, price feeds, exchange rates, geocoding, etc.), all at the same $0.02 price point. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no additional technical detail, so the actual response schema and behavior of this endpoint are not documented.","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 payment API","pay-per-call API","Base network API","lowpaymentfee"],"warnings":["No API documentation available — all doc/pricing/README pages return only 'Connect wallet' with no content.","Endpoint is hardcoded to order 11; unclear if other order IDs are supported or if this is a demo.","No response schema or example response is documented anywhere.","The platform lists many endpoints but none appear to have detailed docs."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/11/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/11/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).
