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/20/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 (the asset at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, which uses 6 decimals), equating to $0.02 per call. Payment is made via the X-PAYMENT header; no API keys or accounts are required. The endpoint responds with application/json.\n\nDocumentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the order status response contains. The platform advertises no rate limits and no minimums, but these claims cannot be independently verified from the crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","order-status","micropayment","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","pay-per-call API","USDC payment API","Base network API","lowpaymentfee","order tracking"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) all return only a 'Connect wallet' prompt with no actual content.","No OpenAPI or schema available — request body format and response structure are unknown.","The endpoint path is hardcoded to order ID 20; it is unclear whether other order IDs are supported or how to discover them.","The platform's broader API offerings (AI, analytics, finance, etc.) are listed but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/20/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/20/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 (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs.
