x402-gated employee salary endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 72) via an x402 payment-gated POST request. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request settled in USDC on the Base network.
The x402 challenge confirms the endpoint is live and accepts the "exact" payment scheme. The maximum amount required is 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
Documentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific purpose of the employee salary endpoint (whether it returns mock/demo data or real payroll information) is unclear from the available material. Treat this as a demonstration or early-stage endpoint until more documentation surfaces.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of the specific employee salary resource is ambiguous. Effectively a stub listing.
Warnings

- —All documentation pages return only 'Connect wallet' with no technical content
- —The nature of the employee salary data (mock, demo, or real) is unknown
