MultiOn: Twitter News Agent

In this example, we use Modal to deploy a cron job that periodically checks for AI news everyday and tweets it on Twitter using the MultiOn Agent API.

Import and define the app

Let’s start off with imports, and defining a Modal app.

import os

import modal

app = modal.App(
    "multion-news-tweet-agent"
)  # Note: prior to April 2024, "app" was called "stub"

Searching for AI News

Let’s also define an image that has the multion package installed, so we can query the API.

multion_image = modal.Image.debian_slim().pip_install("multion")

We can now define our main entrypoint, that uses MultiOn to scrape AI news everyday and post it on our twitter account. We specify a schedule in the function decorator, which means that our function will run automatically at the given interval.

Set up MultiOn

MultiOn is a next-gen Web Action Agent that can take actions on behalf of the user. You can watch it in action here: Youtube demo.

The MultiOn API enables building the next level of web automation & custom AI agents capable of performing complex actions on the internet with just a few lines of code.

To get started, first create an account with MultiOn, install the MultiOn chrome extension and login to your Twitter account in your browser. To use the API create a MultiOn API Key and store it as a modal secret on the dashboard

@app.function(
    image=multion_image, secrets=[modal.Secret.from_name("MULTION_API_KEY")]
)
def news_tweet_agent():
    # Import MultiOn
    import multion

    # Login to MultiOn using the API key
    multion.login(use_api=True, multion_api_key=os.environ["MULTION_API_KEY"])

    # Enable the Agent to run locally
    multion.set_remote(False)

    params = {
        "url": "https://www.multion.ai",
        "cmd": "Go to twitter (im already signed in). Search for the last tweets i made (check the last 10 tweets). Remember them so then you can go a search for super interesting AI news. Search the news on up to 3 different sources. If you see that the source has not really interesting AI news or i already made a tweet about that, then go to a different one. When you finish the research, go and make a few small and interesting AI tweets with the info you gathered. Make sure the tweet is small but informative and interesting for AI enthusiasts. Don't do more than 5 tweets",
        "maxSteps": 100,
    }

    response = multion.browse(params)

    print(f"MultiOn response: {response}")

Test running

We can now test run our scheduled function as follows: modal run multion_news_agent.py.py::app.news_tweet_agent

Defining the schedule and deploying

Let’s define a function that will be called by Modal every day.

@app.function(schedule=modal.Cron("0 9 * * *"))
def run_daily():
    news_tweet_agent.remote()

In order to deploy this as a persistent cron job, you can run modal deploy multion_news_agent.py.
