Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/32` returns JSON data for employee ID 32 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network, with a 300-second timeout.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the employee record contains. The endpoint is confirmed live (402 challenge returned), but the actual data shape and content remain unknown.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation beyond a landing page listing, no example request/response payloads, and no description of what the employee data actually contains. This is effectively a stub listing.
