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 #107 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 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.
The specific endpoint `/api/v1/orders/107/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 (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which has 6 decimals), equating to $0.02 USD. Payment is made via the X-PAYMENT header per the x402 protocol, with a 300-second timeout. No API keys or rate limits are advertised; access is instant once payment is included.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what the order status response actually contains. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what payload to send or what response to expect beyond the stated MIME type of application/json.
