It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs 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 endpoint `/api/v1/orders/45/status` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers must include an X-PAYMENT header with a valid payment proof. The max amount required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys, rate limits, or subscriptions are needed — each call is independently paid.\n\nThe platform advertises no minimums, no commitments, and instant access. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema or detailed request/response documentation available, so the exact input parameters and response shape for this order-status endpoint are unknown.","tags":[],"capabilities":["x402-payment","per-call-micropayment","order-status","usdc-base","json-response","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","order tracking","x402 endpoint","micropayment API","pay-per-call API","USDC payment API","Base network API"],"warnings":["Documentation pages (/docs, /pricing, /api, /README) all render only a 'Connect wallet' prompt with no readable content","No OpenAPI or schema documentation available for request parameters or response format","Endpoint is hard-coded to order ID 45 — unclear if this is a demo or a real resource","The purpose and data behind 'order 45 status' is not documented anywhere in the crawl"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/45/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/45/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).
