Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically record ID 89) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that advertises multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/89) is not documented on the provider's landing page among the advertised APIs. Its exact response schema and the nature of the employee data it returns are unknown; the only confirmed details come from the x402 challenge itself.
The endpoint is live and returns a well-formed x402 challenge (version 1, scheme "exact"). The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a maximum timeout of 300 seconds. Documentation on the site is essentially empty beyond the landing page catalog — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content.
