x402-gated employee salary endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 19) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this translates to $0.02 per call, consistent with the provider's site-wide pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured with a 402 response, confirming the endpoint is live.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all at the same $0.02/request price point. However, this specific endpoint (/api/v1/employees/19/salary) is not listed on the provider's landing page among the advertised API categories, and no documentation or schema details are available for it. The actual response format and the nature of the salary data returned are unknown.
