Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary information for a specific employee (ID 116) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and no upfront commitments — callers simply attach an x402 payment header with each request.
The provider (lowpaymentfee.com) hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/employees/116/salary` endpoint. The response MIME type is `application/json`, and the endpoint accepts POST requests.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data content and request body format are unknown.

Quality
The endpoint is confirmed live with a valid 402 x402 challenge, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond a landing page listing. The specific data returned by this salary endpoint is entirely unknown, making it effectively a stub listing.
