x402-gated employee salary data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via an x402 payment-gated API. The specific resource `/api/v1/employees/130/salary` returns salary information for employee ID 130 in JSON format. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The endpoint accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced uniformly at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access.
Documentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed documentation for this specific employee salary endpoint. The nature of the data returned (mock, synthetic, or real employee records) is not disclosed. Users should exercise caution and verify the data quality before relying on it for any purpose.
