Pay-per-call employee salary data endpoint on Base via x402 (USDC, $0.02/request).
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/83/salary` returns salary information for employee ID 83, paid per-call using USDC on the Base network. The x402 challenge confirms the endpoint is live and accepts payments of up to 20,000 base units of USDC (0.02 USD) per request.
The endpoint is part of a broader platform (lowpaymentfee.com) that hosts dozens of pay-per-call 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. Payment is settled on-chain via the x402 protocol on Base, using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint returns. The endpoint's purpose and response format must be inferred entirely from the URL path and the x402 challenge metadata.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond the landing page listing. The specific endpoint (/employees/83/salary) is not even listed on the homepage — it may be a demo or test resource. Response format is entirely unknown.
