It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and utility categories — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/118/status` is labeled \"Premium API Access\" in the x402 challenge. The payment scheme is \"exact\" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the X-PAYMENT header per the x402 protocol (version 1). No API keys or rate limits are advertised; access is instant once payment is included.\n\nThe broader platform lists endpoints for 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. However, documentation pages (docs, pricing, README) returned only a \"Connect wallet\" prompt with no substantive content, so the actual behavior and response schemas of these endpoints are unknown. The specific utility of an order-status endpoint (order #118) is unclear — it may be a demo or placeholder resource.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-request","lowpaymentfee"],"warnings":["Documentation pages (/docs, /pricing, /README) return no content beyond 'Connect wallet'","No response schema or example responses available for any endpoint","The endpoint targets a specific order ID (118) — unclear if this is a demo/placeholder or a real resource","No OpenAPI or machine-readable schema provided","Actual functionality behind 'Premium API Access' label is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/118/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/118/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).
