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 settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/104/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 (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the X-PAYMENT header per the x402 protocol (version 1). No API keys or rate limits are advertised; access is instant once payment is included.\n\nDocumentation on the site is extremely thin — the docs, pricing, API, 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 detailed description of what the order status response contains. The endpoint appears live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what fields the response includes or what input the POST body expects.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC pay-per-call","Base network API","lowpaymentfee"],"warnings":["Documentation pages (docs, pricing, API, README) all render only 'Connect wallet' with no usable content.","No OpenAPI or schema available — request body and response format are unknown.","Endpoint path is hardcoded to order ID 104; unclear if other order IDs are supported or how to discover them.","The broader platform lists many endpoints (AI, finance, utils) but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/104/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/104/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 and returns a valid x402 challenge, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'.
