In this Blog, we’ll walk through building a LinkedIn Post Generator using the Lyzr SDK, Streamlit for the front-end interface.
This application will allow users to create and publish LinkedIn posts seamlessly by entering their text content and image URL.
We’ll utilize LyzrAgent to interact with Lyzr’s API and harness the power of AI for automating content generation and posting on LinkedIn.
Prerequisites:
Before diving into the code, ensure you have the following:
-Python 3.8 or higher installed.
-Lyzr SDK installed.
-Streamlit installed.
-An OpenAI API key and Lyzr API key.
-A .env file containing your API keys (OPENAI_API_KEY and LYZR_API_KEY).
Setting Up the Environment:
First, let’s set up our environment by loading the necessary libraries and API keys. We’ll create a .env file to securely store our API keys and use the dotenv library to load them into our application.
import os
from lyzr_agent import LyzrAgent
import streamlit as st
from dotenv import load_dotenv
load_dotenv()
OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")
LYZR_API_KEY = os.getenv("LYZR_API_KEY")
Creating the LyzrAgent:
The core of our application is the LyzrAgent, which will be responsible for creating environments, agents, and handling user inputs to generate and post content on LinkedIn.
Agent = LyzrAgent(
api_key=LYZR_API_KEY,
llm_api_key=OPENAI_API_KEY
)
Building the Agent Environment:
We define a function create_agent() to set up the agent's environment. This environment is configured to use the TOOL_CALLING feature and will be equipped with a specific tool for posting images and text to LinkedIn.
@st.cache_resource
def create_agent():
env_id = Agent.create_environment(
name="Post_linkedin",
features=[{
"type": "TOOL_CALLING",
"config": {"max_tries": 3},
"priority": 0
}],
tools=["post_image_and_text_linkedin"]
)
print(env_id)
prompt = """
You are an Expert Linkedin Post Creator. Your task is to compose and publish a LinkedIn post using the user provided Title, Image Url , and Text Content. You must follow these guidelines meticulously:
[prompts here]
agent_id = Agent.create_agent(
env_id=env_id['env_id'],
system_prompt=prompt,
name="Linkedin"
)
print(agent_id)
return agent_id
Handling User Input:
We then use Streamlit’s text_area function to capture the user's input, including the post content and image URL. Upon clicking the "Generate" button, the app calls create_agent() to create an agent and uses the send_message function to generate the LinkedIn post.
query = st.text_area("Give the textual context of the post and the relevant image url.")
if st.button("Generate"):
agent = create_agent()
print(agent)
chat = Agent.send_message(
agent_id=agent['agent_id'],
user_id="default_user",
session_id="akshay@lyzr.ai",
message=query
)
st.markdown(chat['response'])
Defining the LyzrAgent Class:
Finally, we define the LyzrAgent class in lyzr_agent.py. This class handles all interactions with the Lyzr API, including creating environments, agents, and sending messages.
import requests
import json
class LyzrAgent:
def __init__(self, api_key, llm_api_key):
self.url = "https://agent.api.lyzr.app/v2/"
self.headers = {
"accept": "application/json",
"x-api-key": api_key
}
self.llm_api_key = llm_api_key
def create_environment(self, name, features, tools):
payload = json.dumps({
"name": name,
"features": features,
"tools": tools,
"llm_api_key": self.llm_api_key
})
url = self.url + "environment"
response = requests.post(url, headers=self.headers, data=payload)
if response.status_code == 200:
return response.json()
else:
print(f"Error: {response.status_code} - {response.text}")
return None
def create_agent(self, env_id, system_prompt, name):
payload = json.dumps({
"env_id": env_id,
"system_prompt": system_prompt,
"name": name,
"agent_persona": "",
"agent_instructions": "",
"agent_description": ""
})
url = self.url + "agent"
response = requests.post(url, headers=self.headers, data=payload)
if response.status_code == 200:
return response.json()
else:
print(f"Error: {response.status_code} - {response.text}")
return None
def send_message(self, agent_id, user_id, session_id, message):
payload = json.dumps({
"user_id": user_id,
"agent_id": agent_id,
"session_id": session_id,
"message": message
})
url = self.url + "chat/"
response = requests.post(url, headers=self.headers, data=payload)
if response.status_code == 200:
return response.json()
else:
print(f"Error: {response.status_code} - {response.text}")
return None
def create_task(self, agent_id, session_id, input_message):
payload = json.dumps({
"agent_id": agent_id,
"session_id": session_id,
"input": input_message
})
url = self.url + "task"
response = requests.post(url, headers=self.headers, data=payload)
if response.status_code == 200:
return response.json()
else:
print(f"Error: {response.status_code} - {response.text}")
return None
With this setup, you’ve built a simple yet powerful LinkedIn Post Generator using Lyzr and Streamlit. The application takes user input, leverages the power of GPT-4 Turbo, and automates the process of creating and publishing LinkedIn posts.
