Check order status via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns the status of a specific order (order ID 100 in the probed URL pattern) behind an x402 paywall. The provider operates a broad suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request and settled in USDC on the Base network. No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request.
The specific endpoint probed (`/api/v1/orders/100/status`) appears to be an order-status lookup, though the provider's landing page does not list it among its featured API categories. The x402 challenge confirms the endpoint is live, accepting POST requests, and requiring up to 20,000 base units of USDC (0.02 USDC, i.e., $0.02) per call. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a 300-second timeout window.
Documentation is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl. The endpoint's actual response format and the meaning of the order ID path parameter are unknown beyond what can be inferred from the URL structure.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the specific endpoint is not listed among the provider's featured APIs. Effectively a stub listing.
