Zearch runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 13 Oct 2026.
Research with answers you can check: every paragraph verified against its cited source.
Today is the operative word: we check Zearch every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
