Assymetrix runs on your own machine — the client starts it, so there is no endpoint to ping. 387 installs a week from npm. Last commit 28 Oct 2026.
Read-only prediction market data (Polymarket, Kalshi, Limitless) from the Assymetrix Data API.
Today is the operative word: we check Assymetrix every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
