Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request, settled per-call using the x402 payment protocol on the Base network with USDC. The specific resource `/api/v1/employees/128/salary` returns salary information for employee ID 128 in JSON format.
The endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals). Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live, accepting the "exact" payment scheme on Base, paying to address 0x1A2B...85F3 with a 300-second timeout.
lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data/analytics, AI/ML, finance/Web3, and utility services, all priced at $0.02 per request. However, the employee salary endpoint is not listed on the site's public catalog, and no documentation, request/response schema, or example payloads are available. The actual data source and fidelity of the salary information are unknown.
