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 order #2 via a POST request, gated by the x402 payment protocol. It is part of a broader platform that offers a variety of API categories — data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/2/status` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an `X-PAYMENT` header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, with a 300-second timeout window. No API keys or rate limits are required — access is purely pay-per-call.
The platform advertises a uniform $0.02/request pricing model across all its endpoints. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema, no detailed request/response documentation, and no example payloads available from the crawled material. The exact structure of the order status response is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, the endpoint is scoped to a single hardcoded order ID (order 2), there is no OpenAPI schema, no request/response examples, and all documentation pages require wallet connection with no readable content. The purpose and utility of this specific endpoint are unclear.
Warnings
- —Endpoint is hardcoded to order ID 2 — unclear if other order IDs are supported or how to discover them.
- —No OpenAPI schema or request/response documentation available.
- —All doc pages (/docs, /pricing, /api, /README) render only a 'Connect wallet' prompt with no usable content.
- —The broader platform lists many endpoint categories but none were probed; only this single order-status endpoint is confirmed live.
