Pay-per-call employee data API on Base, settled in USDC via x402 protocol.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically record #97) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC at a cost of $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities, all priced uniformly at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/employees/97`) is not documented on the provider's landing page among the advertised API categories. It appears to be an employee record lookup endpoint, but its exact response schema and the nature of the data it returns are not documented.
The x402 challenge is live and well-formed, confirming the endpoint is operational. The payment is routed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract on Base (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The maximum timeout for payment settlement is 300 seconds. No OpenAPI schema, detailed documentation, or example responses are available for this specific endpoint.
