Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary data for a specific employee (ID 148) via a POST request. It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.
The endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 protocol: callers receive a 402 challenge with payment details, submit an X-PAYMENT header with a signed USDC transaction on Base, and receive the JSON response upon settlement. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.
Note that the specific endpoint path (`/api/v1/employees/148/salary`) is not listed on the provider's landing page among the advertised API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). It may be an unlisted or demo endpoint. The docs, pricing, and README pages returned only a "Connect wallet" prompt with no additional documentation, so the exact response schema and input parameters are unknown beyond what the x402 challenge reveals (POST method, application/json output).

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI schema, no example request/response, and the specific employee-salary endpoint is not listed among the provider's advertised APIs. The docs pages are empty beyond a wallet-connect prompt.

- —No documentation, input schema, or response schema available; behavior must be discovered empirically.
