x402-payable employee salary lookup endpoint on Base, settled in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via an x402 micropayment protocol. The specific resource `/api/v1/employees/177/salary` returns salary information for employee ID 177 in JSON format, gated behind a per-request USDC payment on the Base network.
The endpoint is live and returns a standard x402 challenge (HTTP 402) requiring an `X-PAYMENT` header with a payment proof. The maximum amount required per call is 20,000 base units of USDC (0.02 USD), consistent with the site-wide pricing of $0.02 per request. Payment is made to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC at contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base. The timeout for payment settlement is 300 seconds.
The broader lowpaymentfee.com platform advertises a variety of x402-gated API categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all at the same $0.02/request price point. However, the specific employee salary endpoint does not clearly fit into any of these advertised categories, and no documentation describes the schema of the salary response or what data fields are returned. The docs, pricing, and API pages on the site are effectively empty (showing only a "Connect wallet" prompt), so details about request parameters, response format, and the nature of the underlying data are unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation on request parameters, response schema, or what the salary data actually contains. The docs/pricing/API pages are empty. The employee salary endpoint doesn't match any of the advertised API categories, raising questions about its purpose and data source.
Warnings

- —The /api/v1/employees/177/salary path does not appear in the site's advertised API catalog, making its provenance unclear
