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 employee record #90) via the x402 payment protocol. The endpoint 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, this specific endpoint (`/api/v1/employees/90`) is not listed on the provider's landing page among the advertised APIs, and no documentation describes what fields the employee record contains or what the request body should look like. The docs, pricing, and API pages all appear to be behind a wallet-connect gate with no publicly visible content.
Because there is no OpenAPI schema, no example request/response, and no documentation beyond the x402 challenge itself, the actual data returned by this endpoint is unknown. Callers should be aware that the endpoint is live (returns a proper 402 challenge) but its utility cannot be verified without making a paid request.
