x402-gated employee salary data endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 144) via an x402 payment challenge. It is part of a broader platform offering dozens of pay-per-request API endpoints across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers receive a 402 challenge specifying the USDC amount required, then submit an X-PAYMENT header with a signed payment to proceed. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The platform advertises no API keys, no rate limits, and instant access.
Note that the specific endpoint path (`/api/v1/employees/144/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 less-publicized endpoint. No documentation, request schema, or response schema is available beyond the x402 challenge metadata. The actual data returned (salary details, format, fields) is unknown from available materials.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, and the specific endpoint is not listed among the provider's advertised APIs. The actual data returned is completely unknown. Docs pages returned only 'Connect wallet' with no useful content.
