Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/67` returns JSON data for employee ID 67 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base, using the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no description of request parameters or response shape for the employees endpoint, and no examples. The endpoint is live (returns a proper 402 challenge), but the actual data returned after payment is unknown. The platform advertises no API keys, no rate limits, and instant access.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no documentation of request/response shapes, and no examples. The docs pages are empty beyond a wallet connect prompt. The actual data content and structure behind the paywall is unknown.
Warnings

- —No OpenAPI or schema describing request parameters or response format for the employees endpoint
- —Response data structure is completely unknown; cannot verify what employee data is actually returned
- —The endpoint path suggests a demo/sample resource (employee ID 67) — unclear if this is production data
