Pay-per-call employee salary lookup API 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/45/salary` returns salary information for employee ID 45. The x402 challenge confirms the endpoint is live and accepts payments of up to $0.02 per request (20,000 base units of USDC with 6 decimals).
The provider lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payment is handled entirely through the x402 protocol's X-PAYMENT header, meaning callers authenticate and pay in a single HTTP round-trip on the Base L2 network.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint actually returns. The endpoint's purpose and response format must be inferred entirely from the URL path and the generic listing description.

Quality
