Check order status via x402 micropayment on Base (USDC, $0.02/request).
What it does
This endpoint at lowpaymentfee.com returns the status of order #175 via a POST request, gated by an x402 payment challenge. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/175/status` appears to be an order-status lookup. The x402 challenge confirms it is live, accepting USDC (contract 0x8335…2913) on Base with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payment is made via the `exact` scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted per-request upon payment.
Documentation on the site 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 spec, no request/response schema beyond the x402 challenge's `outputSchema` stub, and no examples of what the order-status response actually contains. The platform lists many other endpoints (sentiment analysis, summarization, embeddings, price feeds, geocoding, etc.) at the same $0.02 price point, but none have documented schemas either. Treat this listing as a stub until richer documentation is published.

}Endpoint
Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no response schema, no examples, and the docs pages are empty. The specific endpoint path (/orders/175/status) is hard-coded to a single order ID, which limits general usefulness. Effectively a stub.
Warnings
- —No OpenAPI spec or response schema available — response format is unknown
- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content
- —The endpoint path is hard-coded to order ID 175; unclear if other order IDs are supported or how to discover them
- —Platform lists many endpoints but none have documented request/response contracts
