x402-gated order status endpoint on Base, paying $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides order status information via an x402 payment-gated API. The specific resource `/api/v1/orders/91/status` returns order status data in JSON format when called with a valid x402 payment header. It is part of a broader platform that offers numerous pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is granted purely through the x402 payment flow. The endpoint accepts POST requests and returns application/json responses.
Documentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the order status response contains. The endpoint path suggests it retrieves the status of a specific order (ID 91), but it is unclear whether this is a demo/sample resource or whether callers can substitute arbitrary order IDs. The platform appears to be a demonstration or early-stage deployment of x402-gated microservices.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the specific endpoint path (/orders/91/status) is opaque with no explanation of parameters or response shape. This is effectively a stub listing.
Warnings
- —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or response schema provided; response format is unknown
- —Endpoint path references a hardcoded order ID (91); unclear if other IDs are supported
- —Platform appears to be early-stage or a demo; no SLA or support information available
