x402-payable endpoint returning employee salary data on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via the x402 payment protocol. Specifically, the path `/api/v1/employees/54/salary` returns salary information for employee ID 54 when called with a POST request and a valid X-PAYMENT header settling in USDC on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that hosts dozens of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the "exact" scheme, with a 300-second timeout.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live (402 challenge returned), but the actual response format and the data returned after successful payment are unknown. The platform advertises no API keys, no rate limits, and instant access.
