Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary information for a specific employee (ID 180) via a POST request. It is part of a broader platform offering dozens of pay-per-call API endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all settled on the Base network using USDC.
The endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed payment proof, and the server verifies it before returning the response. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.
The specific endpoint `/api/v1/employees/180/salary` is not listed on the provider's landing page among the advertised API categories (analytics, AI, finance, infrastructure), so its exact response schema and data source are unknown. The probe confirms it is live and returns a valid x402 challenge with version 1, accepting the "exact" payment scheme on Base mainnet. The payTo address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` and the accepted asset is USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no additional technical detail.
