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

In the world of quantitative finance and trading, understanding market sentiment is crucial, especially in volatile sectors like energy. Parsing through countless news articles and social media posts can be a daunting and time-consuming task. Luckily, there's a better way to handle sentiment analysis without resorting to DIY scraping.

The Problem (DIY scraping pain)

When it comes to sentiment analysis, you typically face several hurdles:

1. Volume of Data: The energy sector generates a massive amount of news and social media chatter, making it impossible to manually track.
2. Quality of Data: Not all sources are reliable, and scraping can lead to inconsistent data quality.
3. Maintenance: Scraping scripts require constant updates to handle changes in website structures, which is tedious.

This is where a dedicated API can save you time and resources. Instead of reinventing the wheel, you can leverage existing solutions to get the job done.

The Solution (Pulsebit API — one endpoint)

Enter the Pulsebit API. This API provides a straightforward endpoint to analyze sentiment around various topics, including energy. You can get insights quickly and easily without worrying about the backend complexities.

To get started, you’ll primarily be using the /news_semantic endpoint. This endpoint returns sentiment analysis based on the most recent news articles related to your topic of interest.

The Code (Python GET /news_semantic)

Here's a simple Python script to get you started with the Pulsebit API:

import requests

# Define the API endpoint and your API key
url = "https://api.pulsebit.co/news_semantic"
api_key = "YOUR_API_KEY"  # Replace with your actual API key

# Define the parameters for the request
params = {
    'topic': 'energy',  # You can change this to any topic you're interested in
    'language': 'en',
}

# Make the GET request
response = requests.get(url, headers={'Authorization': f'Bearer {api_key}'}, params=params)

# Check if the request was successful
if response.status_code == 200:
    data = response.json()
    print(data)
else:
    print("Error:", response.status_code, response.text)

Make sure to replace YOUR_API_KEY with your actual Pulsebit API key. This script will fetch the latest sentiment data for the energy sector.

Reading the Response

Once you run the above code, you will receive a JSON response that looks something like this:

{
    "sentiment": 0.00,
    "momentum": 0.71,
    "clusters": 0,
    "confidence": 0.87
}

Here’s what each field means:

• sentiment: The overall sentiment score for the energy sector. A score of 0.00 indicates neutral sentiment. Positive values indicate optimism, while negative values indicate pessimism.

• momentum: This score (0.71 in this case) indicates the rate of change in sentiment over time. A score above zero suggests that sentiment is becoming more positive.

• clusters: This indicates the number of distinct sentiment clusters identified in the data. In our example, 0 clusters suggest a lack of significant divergence in sentiment.

• confidence: This score (0.87) reflects the model's confidence in the sentiment assessment. A higher score indicates a more reliable result.

Three Use Cases

Here are three practical use cases for integrating the Pulsebit API into your workflow:

1. Algo Trading Alerts: Implement a trading algorithm that triggers buy/sell signals based on sentiment shifts. For instance, you could set a threshold to execute trades if sentiment crosses a certain positive or negative value.

2. Slack Bot Notifications: Build a Slack bot that sends real-time notifications when sentiment changes significantly, helping your team stay informed without manual checks.

3. Dashboard Integration: Create a dashboard that visualizes sentiment trends over time, allowing you to make data-driven decisions based on real-time insights.
