x402-gated employee salary data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 166) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-gated APIs across data & analytics, AI & ML, finance & Web3, and infrastructure categories — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. However, the specific endpoint being listed here (`/api/v1/employees/166/salary`) is not mentioned on the provider's landing page among the advertised API categories, which raises questions about its intended use and whether it returns real or demo data.
Documentation is extremely sparse. The /docs, /api, /pricing, 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 x402 challenge), but the lack of documentation makes it difficult to know what to expect from a successful paid request.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no schema, no examples, no description of response fields. The specific employee salary endpoint is not listed among the provider's advertised APIs, raising uncertainty about whether it serves real or demo data. Score reflects a stub-level listing.
