How to Detect Startups Sentiment Shifts with the Pulsebit API (Python)

The Problem

As a developer diving into the world of startup sentiment analysis, you’ve probably faced the tedious and often unreliable process of DIY scraping. You know the struggle: parsing through vast amounts of data from multiple sources, dealing with rate limits, and ensuring data accuracy. It’s a pain that takes away from your core focus—building and iterating on your product.

Today, I want to share a powerful solution to streamline this process using the Pulsebit API. This API provides a single endpoint that can give you valuable insights into sentiment shifts in the startup ecosystem, allowing you to focus on what really matters.

The Solution

The Pulsebit API offers an endpoint /news_semantic that returns structured sentiment data for various topics, including startups. With this, you can easily access and analyze sentiment trends without the hassle of scraping.

Let’s look at the current data:

• Sentiment Score: +0.00
• Momentum (24h): +1.27
• Semantic Clusters: 10
• Confidence: 0.87

What’s noteworthy here is the momentum score of +1.27 despite a flat sentiment score of +0.00. This indicates that while the overall sentiment might be neutral, there’s a rising momentum in discussions around startups. That’s an unusual scenario that should grab your attention.

The Code

To get started, you’ll want to make a simple GET request to the /news_semantic endpoint. Here’s how you can do that using Python with the requests library:

import requests

def get_startup_sentiment(api_key):
    url = 'https://pulsebit.lojenterprise.com/api/news_semantic'
    headers = {
        'Authorization': f'Bearer {api_key}'
    }

    response = requests.get(url, headers=headers)

    if response.status_code == 200:
        return response.json()
    else:
        raise Exception(f'Error: {response.status_code} - {response.text}')

# Replace 'your_api_key' with your actual Pulsebit API key
data = get_startup_sentiment('your_api_key')
print(data)

This code will fetch the sentiment data for startups from Pulsebit.

Reading the Response

Once you receive the response, you’ll notice several fields that provide crucial insights:

• sentiment_score: The overall sentiment, which is currently at +0.00. This indicates a neutral sentiment.
• momentum_24h: At +1.271, this shows a rising interest or activity surrounding startups, even if the sentiment is neutral.
• confidence: A value of 0.87 suggests a high level of certainty in the data provided.
• semantic_clusters: The API has identified 10 clusters, indicating diverse discussions around various aspects of startups.
• region: This is marked as global, meaning the sentiment applies to startups worldwide.
• semantic_similarity_avg: At 0.185, this reflects the average similarity among the identified semantic clusters.

Three Use Cases

Now that you have the data, how can you leverage it?

1. Algo Alert: Set up an alert that triggers when momentum crosses a specific threshold (e.g., >1.0). This can help you catch trends early.

2. Slack Bot: Build a Slack bot that posts daily updates on startup sentiment. You can format the output based on the momentum and sentiment score, providing instant insights to your team.

3. Dashboard: Create a dashboard that visualizes sentiment trends over time. You can plot momentum versus sentiment score to identify correlations and shifts in startup discussions.
