This example shows a subset of an AI Agent with Restate.

Restate is a system for easily building resilient applications using distributed durable building blocks.

❓ Learn more about Restate from the Restate documentation.

Running the example

To set up the example, use the following sequence of commands.

Setup the virtual env:

cd backend
python3 -m venv .venv
source .venv/bin/activate

Install the requirements:

pip install -r requirements.txt

Export you OpenAI key and then start the app as follows:

export OPENAI_API_KEY=your_openai_key
python3 backend/main.py

Start the Restate Server (other options here):

restate-server

Register the service:

restate dp register http://localhost:9080

Interacting with the chatbot via the UI

cd ui
npm i 
npm run dev

Then open the browser at http://localhost:3000/ and interact with the chatbot.

For example, you can type:

Hey, I am Malik, can you set an alarm in one minute to drink water?

Or:

Hey, I am Malik, can you set an alarm for the flight price of start airport Berlin to destination airport Vilnius for next week Tuesday 6 August 2024 and return date 8 August 2024 in first class with a maximum of 200 euro as price threshold?

Interacting with the chatbot via HTTP

You can also interact with the chatbot via HTTP, but you won't be able to receive async responses.

For example, you can use curl to send a message to the chatbot:

curl localhost:8080/ChatSession/Malik/onMessage  --json '"Hey, I am Malik, can you set an alarm in one minute to drink water?"'

Or:

curl localhost:8080/ChatSession/Malik/onMessage  --json '"Hey, I am Malik, can you set an alarm for the flight price of start airport Berlin to destination airport Vilnius for next week Tuesday 6 August 2024 and return date 8 August 2024 in first class with a maximum of 200 euro as price threshold?"'

Or:

curl localhost:8080/ChatSession/Malik/onMessage  --json '"What is the best offer so far for task id flight_price_berlin_vilnius"'

That's it! We managed to run the example, interact with the chatbot, and run tasks!
