x402-gated employee salary endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 138) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the provider's site-wide pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access; you simply attach an X-PAYMENT header with a valid x402 payment proof.
lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data/analytics, AI/ML, finance/Web3, and utility endpoints, all at the same $0.02 price point. However, this specific endpoint (/api/v1/employees/138/salary) is not listed on the provider's landing page among the advertised APIs. There is no documentation, schema, or example response available for this endpoint — the docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. The actual structure of the salary data returned is unknown.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, this specific endpoint is not listed among the provider's advertised APIs, there is no documentation, no request/response schema, and no example data. The docs pages are empty beyond a wallet-connect prompt. Effectively a stub with confirmed liveness.
