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 #158) 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 at $0.02 per request. However, this specific endpoint (/api/v1/employees/158) is not listed among the advertised categories on the landing page, and no documentation describes the employee data schema or what fields are returned. The response MIME type is application/json.
Because the endpoint is live (returning a proper 402 challenge) but lacks any documentation about the employee data model, request parameters, or response schema, consumers should treat this as a minimally documented resource. The platform's docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical content.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payments. However, there is zero documentation on the employee data model, no OpenAPI schema, no example responses, and the endpoint path (/api/v1/employees/158) does not appear in the provider's own advertised API catalog. The docs/pricing/README pages are empty beyond a wallet connect prompt.
