It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request, settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/197/status` accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation pages (docs, pricing, README) all resolve to a minimal \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no example request/response payloads, and no description of what the order status response actually contains. The endpoint path is hardcoded to order 197, so it is unclear whether this is a demo/example or a production resource. The broader site lists many other endpoints across analytics, AI, finance, and utility categories, all at the same $0.02 price point.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","pay-per-request"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /pricing, /README) all return only a 'Connect wallet' prompt with no actual content.","Endpoint is hardcoded to order ID 197 — unclear if this is a demo or a real resource.","No OpenAPI spec, no example responses, and no description of the response schema.","No information about what 'order status' actually returns or what data model it follows.","The broader platform lists many endpoints but none have documented schemas."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/197/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/197/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).
