x402-gated employee data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an employee record (ID 93) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utility categories — all priced at $0.02 per request, settled in USDC on the Base network.
The specific resource `/api/v1/employees/93` returns JSON and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet. No API keys, rate limits, or upfront commitments are required.
Documentation on the site 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 spec, no request/response schema documentation, and no explanation of what the employee data contains or what fields are returned. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data payload and its usefulness remain unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what the employee data contains. The docs pages are all empty wallet-connect stubs. This is effectively a stub listing.
