Retrieve employee salary data via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 174) behind an x402 paywall. It accepts POST requests and settles payments in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per call.
The provider lowpaymentfee.com hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This particular endpoint falls under what appears to be an employee/HR data category, though the provider's landing page does not explicitly list it among its featured API groups.
Because the endpoint path references a hardcoded employee ID (174), it is unclear whether callers can query arbitrary employee IDs or whether this is a demo/sample resource. No OpenAPI schema, request body documentation, or response examples were found in the crawl. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content. Treat this endpoint as live but poorly documented.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response documentation, no examples, and the docs pages are empty. The specific purpose (employee 174 salary) is narrow and unexplained.
Warnings

- —This endpoint is not listed among the provider's featured API categories on the landing page.
