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 #131 via a POST request, gated by an x402 payment challenge. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/131/status` accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
The platform advertises no API keys, no rate limits, and instant access. However, documentation pages beyond the landing page are essentially empty (showing only "Connect wallet"), so there is no detailed schema, request/response format documentation, or usage examples available. The endpoint is live and returning a proper 402 challenge, but the actual response payload structure for a successful paid request is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, but documentation is essentially nonexistent beyond the landing page. No request/response schemas, no examples, and the endpoint path is hardcoded to a single order ID (131), making its general utility unclear. Pricing is clear at $0.02/request.
Warnings
- —Documentation pages (/docs, /api, /pricing, /README) all return only 'Connect wallet' with no actual content.
- —No OpenAPI spec or request/response schema available — actual response format is unknown.
- —Endpoint path is hardcoded to order 131; unclear if this is parameterized or a demo-only resource.
- —No information on what 'order' refers to in this context.
