Check order status via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns the status of order #87 via a POST request, gated behind an x402 payment challenge. It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, 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/87/status` is labeled "Premium API Access" in the x402 challenge. The payment scheme is "exact" with a maxAmountRequired of 20,000 base units of USDC (the asset at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, which uses 6 decimals), equating to $0.02 per call. No API keys are required; callers authenticate purely via the X-PAYMENT header containing a signed payment proof. The endpoint responds with application/json.
The platform advertises no rate limits, no minimums, and instant access. Documentation pages (/docs, /pricing, /api, /README) all appear to require a wallet connection and contain no additional textual content in the crawl. There is no OpenAPI schema or ai-plugin manifest available. Because this endpoint is hardcoded to a single order ID (87), its general utility is unclear — it may be a demo or placeholder rather than a parameterized order-status service.

Quick start

-H "Content-Type: application/json"Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, the endpoint is hardcoded to a single order ID with no documented request/response schema, no OpenAPI spec, and all documentation pages are empty behind a wallet gate. Its general utility is questionable.
Warnings
- —Endpoint is hardcoded to order ID 87 — unclear if this is parameterizable or a demo
- —No OpenAPI schema or response examples available
- —All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no usable content
- —No input or output schema beyond the x402 challenge metadata
- —The broader platform lists many endpoints but none have documented schemas
