It is part of a broader platform that offers a variety of API categories — data & analytics, AI & machine learning, 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/2/status` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an `X-PAYMENT` header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, with a 300-second timeout window. No API keys or rate limits are required — access is purely pay-per-call.\n\nThe platform advertises a uniform $0.02/request pricing model across all its endpoints. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema, no detailed request/response documentation, and no example payloads available from the crawled material. The exact structure of the order status response is unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC payment API","Base network API","pay-per-request"],"warnings":["Endpoint is hardcoded to order ID 2 — unclear if other order IDs are supported or how to discover them.","No OpenAPI schema or request/response documentation available.","All doc pages (/docs, /pricing, /api, /README) render only a 'Connect wallet' prompt with no usable content.","The broader platform lists many endpoint categories but none were probed; only this single order-status endpoint is confirmed live."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/2/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/2/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 and returns a valid x402 402 challenge, confirming it works.
