Building a Twitter AI Agent with n8n, FastAPI, and Tweepy

In recent years, Twitter's open API has opened up exciting possibilities for developers to create intelligent agents capable of interacting with users. In this post, we’ll explore how to build a Twitter AI agent utilizing n8n for the automation, FastAPI as the web framework, and Tweepy as our library for interacting with the Twitter API. This approach will help you streamline your automation processes, enhance engagement, and provide rich interactions with users on Twitter.

Prerequisites

To get started, ensure you have the following:

• Basic knowledge of Python and APIs
• An active Twitter Developer account with API keys and tokens
• n8n installed: You can use n8n Cloud or self-host it
• Python environment with FastAPI and Tweepy installed

Setting Up Tweepy for Twitter API Interactions

First, let’s set up Tweepy to connect to the Twitter API. Install Tweepy using pip:

pip install tweepy

Here's how to set up Tweepy:

import tweepy

# Authentication details (replace with your own tokens)
API_KEY = 'your_api_key'
API_SECRET_KEY = 'your_api_secret_key'
ACCESS_TOKEN = 'your_access_token'
ACCESS_TOKEN_SECRET = 'your_access_token_secret'

# Authentication
auth = tweepy.OAuthHandler(API_KEY, API_SECRET_KEY)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)

# Create API object
api = tweepy.API(auth)

# Test the connection
try:
    api.verify_credentials()
    print("Authentication OK")
except:
    print("Authentication Failed")

This code authenticates you with the Twitter API, allowing you to interact with Twitter's endpoints.

Creating a FastAPI Application

Next, let's create a FastAPI application that will handle incoming requests:

from fastapi import FastAPI, HTTPException

app = FastAPI()

@app.get("/bot")
async def get_bot_status():
    return {"status": "Running"}

# Running the app
if __name__ == '__main__':
    import uvicorn
    uvicorn.run(app, host="0.0.0.0", port=8000)

This simple FastAPI application has one endpoint that returns the bot's running status.

Integrating n8n to Automate Responses

After setting up Tweepy and FastAPI, we’ll use n8n to automate responses based on incoming tweets. Here’s how to connect n8n:

1. Create a New Workflow: Log into n8n and create a new workflow.
2. Twitter Trigger Node: Use the Twitter node to trigger the workflow when a new tweet is mentioned. You need to set up your Twitter API credentials in n8n.
3. HTTP Request Node: After the Twitter trigger, create an HTTP request node to communicate with your FastAPI application. Set it to send details about the tweet or request.
4. Processing Logic: Implement any necessary processing logic (e.g., analyzing the tweet, determining a response).
5. Replying with Tweepy: Use the same Tweepy setup to post replies to tweets based on your processing.

Conclusion

Building your Twitter AI agent allows for creative interactions with users while automating repetitive tasks. By leveraging n8n, FastAPI, and Tweepy, you can create a robust solution tailored to your needs. As you evolve your agent with more advanced features, consider integrating AI to handle sentiment analysis or automated content generation. Happy coding!
