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 information for a specific employee (ID 95) via a POST request. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — 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 containing a signed USDC transfer 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/95/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 internal or demo endpoint. The landing page documentation is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available from the crawled material.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the specific endpoint path is not listed among the provider's advertised APIs. Effectively a stub with minimal verifiable information.
