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/169/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 markets itself as requiring no API keys, no rate limits, and no commitments — just per-request micropayments. However, documentation is extremely thin: the /docs, /api, /pricing, and /README pages all render only a \"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 169, so it is unclear whether this is a demo/sample endpoint or a production resource.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","order-status","per-request-billing","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC payment API","pay-per-call API","Base network API"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) contain no substantive content — only 'Connect wallet' prompts.","No OpenAPI or schema describing request body or response format.","Endpoint is hardcoded to order ID 169; unclear if other order IDs are queryable or if this is a demo.","No information about what the order status response payload contains.","Platform lists many other API endpoints (AI, finance, utils) but this specific endpoint is an order status check — purpose and context are unclear."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/169/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/169/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 captured) and pricing is clear ($0.02 USDC on Base).
