{"id":"2d9f4492-5442-483c-bb4b-506ddad0035d","shortId":"bw36Z4","kind":"x402","title":"Check order status via x402 micropayment on Base for $0.02 per request.","tagline":"Check order status via x402 micropayment on Base for $0.02 per request.","description":"This endpoint at lowpaymentfee.com returns the status of order #122 via an x402-gated POST request. It is part of a broader platform that offers a variety of API endpoints across data & analytics, AI & machine learning, finance & Web3, and infrastructure categories — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/122/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 x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), which equals $0.02 given USDC's 6 decimals. The payment timeout is 300 seconds.\n\nThe platform advertises no API keys, no rate limits, and instant access. 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 request/response examples, and no explanation of what data the order status endpoint actually returns or what input it expects beyond a POST body. The endpoint path is hardcoded to order 122, which raises questions about whether this is a demo/example or a genuinely useful production endpoint.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","json-response","post-method"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC payment","pay-per-call API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) all render only 'Connect wallet' with no actual content","No OpenAPI or schema documentation available","Endpoint is hardcoded to order ID 122 — unclear if other order IDs are supported or how to discover them","No request body schema or response examples available","Platform appears to be a demo or early-stage project"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/122/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/122/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 (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base).
