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 175) 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 to each request.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request and all using the x402 protocol on Base. This particular endpoint (`/api/v1/employees/175/salary`) is not listed on the site's public landing page among the advertised API categories, which raises questions about whether it is a demo/test endpoint or part of an unlisted HR data service.
Documentation is extremely sparse. The docs, pricing, API, and README pages all render 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 response contains. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation or sample responses, integrators will need to experiment to understand the response format.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation. The endpoint path (employees/175/salary) is not listed among the site's advertised APIs, making its purpose and data source unclear. Effectively a stub listing.
