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

Understanding business sentiment is crucial for making informed decisions. However, scraping the web for sentiment data can be a pain. This article will show you how to leverage the Pulsebit API to detect sentiment shifts effortlessly.

The Problem (DIY scraping pain)

As developers, we've all been there: writing scrapers to collect sentiment data from various news sources. This often involves:

1. Managing multiple requests to different websites.
2. Handling changes in website structures that break your scrapers.
3. Processing and normalizing the data to extract meaningful insights.

This DIY approach can lead to wasted time and effort, especially when your goal is simply to understand business sentiment. Instead of reinventing the wheel, why not use an API specifically designed for this purpose?

The Solution (Pulsebit API — one endpoint)

Enter the Pulsebit API. With a single endpoint, you can access a wealth of sentiment data without the hassle of scraping. The /news_semantic endpoint provides insights into business sentiment, momentum, clusters, and confidence levels.

Here’s a quick rundown of the metrics you can get:

• Business Sentiment: A score indicating overall sentiment (range: -1.0 to +1.0).
• Momentum: Indicates the rate of change in sentiment.
• Clusters: Represents the number of distinct sentiment groups found in the data.
• Confidence: The reliability of the sentiment score (range: 0.0 to 1.0).

For instance, the current data shows:

• Business Sentiment: +0.00
• Momentum: +0.60
• Clusters: 0
• Confidence: 0.87

The Code (Python GET /news_semantic with code blocks)

Here's how you can interact with the Pulsebit API using Python. You'll need the requests library, so make sure to install it if you haven't already:

pip install requests

Now, let's fetch the sentiment data:

import requests

def get_business_sentiment(api_key):
    url = "https://api.pulsebit.co/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 fetching data: {response.status_code} - {response.text}")

# Replace 'your_api_key' with your actual API key
sentiment_data = get_business_sentiment('your_api_key')
print(sentiment_data)

Reading the Response

The response from the API will contain several fields. Here’s how to interpret each one:

• business_sentiment: This field provides the overall sentiment score. A score of +0.00 indicates neutrality, meaning there’s no significant positive or negative sentiment.
• momentum: At +0.60, this indicates a positive momentum in sentiment, suggesting an upward trend.
• clusters: A value of 0 means no distinct sentiment groups were identified, which could imply a lack of polarized opinions.
• confidence: A confidence level of 0.87 signifies a high degree of reliability in the sentiment score.

Three Use Cases

1. Algo Alert: Set up an algorithmic trading alert for when sentiment shifts beyond a certain threshold, e.g., when sentiment goes below -0.5 or above +0.5.

2. Slack Bot: Create a Slack bot that posts sentiment updates in a channel, keeping your team informed in real-time.

3. Dashboard: Integrate the API into a dashboard that visualizes sentiment changes over time, allowing for easy tracking and analysis.
