Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request, paid per call using the x402 protocol. The specific resource `/api/v1/employees/20/salary` returns salary information for employee ID 20 in JSON format. Payment is settled in USDC on the Base network.
The x402 challenge indicates a maximum cost of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and instant access. The site offers a wide catalog of endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all using the same x402 payment model on Base.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint actually returns. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know the expected request body or response structure without experimentation.

Quality
