It is part of a broader platform that offers a variety of API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/174/status` is labeled \"Premium API Access\" in the x402 challenge. Payment is handled via the x402 exact scheme: the caller includes an X-PAYMENT header with a USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the specified payTo address on Base. No API keys or rate limits are required; access is granted per-request upon valid payment. The response MIME type is application/json.\n\nThe platform advertises a uniform $0.02/request pricing model with no minimums, no commitments, and no API keys. Other endpoints on the same domain cover sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt, so detailed request/response schemas for this specific order-status endpoint are not available.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","per-request-micropayment","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 order lookup","micropayment API","pay-per-call API","Base USDC API","lowpaymentfee"],"warnings":["Endpoint is hardcoded to order ID 174 — unclear if it generalizes to other orders","No request or response schema documented; output format is unknown","All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content","The platform lists many endpoints but none have detailed docs available from the crawl"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/174/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/174/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).
