It is part of a broader platform that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/166/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 x402 protocol's X-PAYMENT header, with no API keys or rate limits required. The endpoint accepts POST requests and returns application/json.\n\nNote that while the platform advertises many endpoint categories (analytics, AI, finance, infrastructure), the specific endpoint being listed here is an order-status lookup. Documentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (402 challenge captured successfully).","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","order tracking","402 payment endpoint"],"warnings":["No API documentation available; /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","Endpoint is hardcoded to order ID 166 — unclear if other order IDs are supported or how to discover them","No request body schema or response schema documented anywhere","The 'Premium API Access' label is generic and does not describe what the endpoint actually returns","Platform advertises many API categories but no evidence any of them have real backing services"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/166/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/166/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 challenge, but documentation is essentially nonexistent — no request/response schemas, no OpenAPI spec, and all doc pages render only 'Connect wallet'.
