How to get an OpenRouter API key
OpenRouter gives you one key that can call almost any model from any provider — handy if you want to try several without signing up for each one separately.
Steps
Go to OpenRouter
Open openrouter.ai and sign in with Google or GitHub.
Open your keys page
Click your avatar (top right), then Keys — or go straight to openrouter.ai/keys.
Create a key
Click Create Key, name it "TalkingSheet", and confirm.
Copy it immediately
Your key (it starts with sk-or-v1-) is shown once — copy it before closing the dialog.
Add credits
OpenRouter is prepaid. Go to Settings → Credits and add funds before your first real request.
Now add it to TalkingSheet
Open the add-on sidebar → Settings → turn on Use my own API key → pick OpenRouter → paste your key → Save. Your key stays in your own Google account's storage — it never touches TalkingSheet's servers. See how BYOK works for details.
