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/198/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 challenge advertises a max amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The 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. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional crawlable content, so the exact response schema and detailed docs for this order-status endpoint are unknown. The endpoint is live and returning a well-formed 402 challenge.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC API","pay-per-call","lowpaymentfee"],"warnings":["Documentation pages (/docs, /pricing, /api) are gated behind wallet connection and contain no crawlable content.","The endpoint path is hardcoded to order ID 198; it is unclear whether other order IDs are supported or how to discover them.","No response schema or example response is available — the output format is unknown.","No OpenAPI or machine-readable API specification was found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/198/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/198/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 and returns a valid x402 challenge, but there is no OpenAPI schema, no response examples, and all documentation pages are behind a wallet-connect gate.
