Your Polymarket US API key
PolyWasp needs it even for paper trading, because Polymarket only serves live prices to signed requests. Create one at polymarket.us/developer. The key is checked against Polymarket, saved only on your computer, and never sent to PolyWasp. Anyone with your key can trade your account, so keep it private.
