Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #138) via the x402 payment protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units 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/138`) is not documented on the provider's landing page among the advertised API categories. It appears to be a resource-specific endpoint returning data for a single employee record.
Because there is no OpenAPI schema, no response examples, and no documentation beyond the x402 challenge and the site's generic landing page, the exact shape of the response and the nature of the employee data returned are unknown. The endpoint is confirmed live (returns a proper 402 challenge), but callers should be aware that the data content and schema are undocumented.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, the specific /api/v1/employees/138 path is not listed among the provider's documented APIs, there is no OpenAPI schema, no response examples, and the docs/pricing/README pages all render only a 'Connect wallet' stub. The data returned is entirely unknown.
