Three Ways to Configure
Pick any one — beginners should start with method 1.
Method 1: Paste in the Web UI (recommended for beginners)
After the service starts, open http://localhost:8765, paste the key into the input box at the top of the page and save — it takes effect immediately.
Method 2: Environment variable AGNES_API_KEY
Best for Docker and server deployments — the key never lands in the UI.
export AGNES_API_KEY="your-api-key" # Or prefix the start command: AGNES_API_KEY=your-api-key ./start.sh
Method 3: Set via API
Equivalent to filling in the Web UI — good for scripted configuration.
curl -X POST http://localhost:8765/api/config \
-H "Content-Type: application/json" \
-d '{"api_key": "your-api-key"}'How to Verify the Key Works
- Save it and start generating — if the key is wrong, generation returns a 401 error.
- Don't copy extra spaces around the key; a stray space breaks authentication.
Where You Can Use the Key
- Official website online demo (no installation — paste the key and go)
- Locally deployed Agnes Video Generator (see the self-hosting guide)
- Web-based Studio (assemble scenes in your browser)
- Direct Agnes API calls (see the API docs and call guide)
