x402-gated employee salary endpoint on Base, paying $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data behind an x402 paywall. The specific resource `/api/v1/employees/25/salary` returns salary information for employee ID 25 via a POST request. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per call. The platform advertises no API keys, no rate limits, and instant access. However, the specific employee salary endpoint is not listed on the provider's landing page among the advertised API categories, which raises questions about whether it is a demo/test resource or a production endpoint.
Documentation is extremely sparse. The /docs, /pricing, /api, 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 description of what fields the salary response contains. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means consumers must discover the response format empirically.
