Usage

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Set Environment Variables

Use this secret as secret_token when registering the public webhook in the setup guide. Keep the same value in the server and registration terminals. APP_ENV=development bypasses webhook authentication, so clear it for this public callback flow.

export TELEGRAM_TOKEN=your-bot-token-from-botfather
export OPENAI_API_KEY=your-openai-api-key
export TELEGRAM_WEBHOOK_SECRET_TOKEN=replace-with-a-long-random-secret
unset APP_ENV

Install dependencies

uv pip install -U "agno[os,telegram]" openai ddgs

Run Example

python reasoning_agent.py

The bot needs a public webhook URL to receive messages. See Telegram setup.
