Sifting runs on your own machine — the client starts it, so there is no endpoint to ping. 40 installs a week from npm. Last commit 11 Jul 2026.
Live crypto/forex/metals prices, OHLCV bars, SEC fundamentals, 13F holdings and econ calendar.
Nothing serious here today
Today is the operative word: we check Sifting every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
