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 and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/3/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, 6 decimals), which equals $0.02. Payment is made via the X-PAYMENT header per the x402 protocol. No API keys, rate limits, or subscriptions are required — each call is independently paid.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, gas estimates, geocoding, validation, conversion, and data export, all at the same $0.02/request price point. However, documentation beyond the landing page is essentially empty (pages like /docs, /pricing, and /api only show a \"Connect wallet\" prompt), so the actual functionality and response schemas of these endpoints are unverified.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","micropayment API","USDC payment API","Base network API","pay-per-call","lowpaymentfee"],"warnings":["Endpoint path is hardcoded to order ID 3 — unclear if it generalizes to other order IDs","All documentation pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no actual content","No response schema or example response is available — actual output format is unknown","The platform lists many endpoints but none have documented schemas or verified functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/3/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/3/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 and returns a valid x402 402 challenge, but the path is hardcoded to a single order ID (3), documentation pages are empty stubs, and there is no response schema, example output, or OpenAPI spec.
