It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific resource `/api/v1/orders/177/status` is labeled \"Premium API Access\" in the x402 challenge. The challenge advertises a maxAmountRequired of 20,000 base units of USDC (token contract 0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 \"exact\" scheme with no API keys, no rate limits, and no subscriptions required — callers simply attach an X-PAYMENT header to each request.\n\nThe platform's landing page lists additional endpoints across four categories (Data & Analytics, AI & Machine Learning, Finance & Web3, Infrastructure), all at the same $0.02 price point. Documentation pages beyond the landing page appear to require a wallet connection and contain no further technical detail. No OpenAPI spec, request/response schemas, or usage examples were found in the crawl, so the exact shape of the order-status response is unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","premium API access","order tracking"],"warnings":["No OpenAPI or schema documentation available; response format is unknown.","Endpoint path is hard-coded to order 177 — unclear if it generalizes to other order IDs.","All documentation pages beyond the landing page returned only 'Connect wallet' with no content.","No rate-limit, SLA, or uptime guarantees documented."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/177/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/177/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 confirmed) and pricing is clear ($0.02 USDC on Base).
