Pay-per-call employee salary lookup API on Base via x402, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple 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 endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint `/api/v1/employees/8/salary` returns salary information for employee ID 8. The x402 challenge indicates a maximum cost of 0.02 USDC per request (20,000 base units with 6 decimals for USDC). The platform advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to your POST request.
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 description of what fields the salary endpoint returns or what input it expects. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data behind it and its accuracy are unknown.
