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

The Problem

If you’re like me, the struggle of scraping sentiment data for environmental topics has led to more headaches than breakthroughs. Traditional methods often involve juggling multiple APIs or web scraping from various sources, each with its quirks and inconsistencies. The data can be stale, unreliable, or just plain hard to interpret. You need real-time insights, not yesterday’s news.

But what if there was a single API endpoint that could give you a clear picture of the current sentiment surrounding environmental issues? Spoiler alert: there is.

The Solution

Enter the Pulsebit API. With just one endpoint, you can tap into a wealth of sentiment data that’s updated frequently. This allows you to detect shifts in sentiment quickly and accurately. Today, we’ll focus on the /news_semantic endpoint, which provides a treasure trove of information about the environment sentiment.

Current Sentiment Snapshot

Let’s look at the current data we have:

• Sentiment Score: +0.375
• Momentum: +1.400
• Confidence: 0.870
• Semantic Clusters: 0

Notably, the sentiment score is +0.375, and with a momentum of +1.400, we can see it’s rising rapidly. This is a significant spike compared to the historical average, which typically hovers around 0.25.

The Code

Here’s how you can fetch this data using Python. Make sure you have the requests library installed. If you don’t, install it using pip install requests.

import requests

def fetch_environment_sentiment():
    url = 'https://pulsebit.lojenterprise.com/api/news_semantic'
    params = {
        'topic': 'environment',
        'region': 'global'
    }
    response = requests.get(url, params=params)

    if response.status_code == 200:
        return response.json()
    else:
        raise Exception(f"Error fetching data: {response.status_code}")

data = fetch_environment_sentiment()
print(data)

Reading the Response

Let’s break down the response you’ll receive from the API:

• sentiment_score: Reflects the overall sentiment towards the environment. A positive score (+0.375) indicates a generally favorable outlook.
• momentum_24h: Measures how quickly sentiment is changing. A value of +1.400 means sentiment is gaining traction rapidly.
• confidence: This tells you how confident the API is in its sentiment reading. Here, it's at 0.870, which is quite high.
• semantic_clusters: Indicates the number of distinct themes identified in the sentiment data. Zero clusters mean a broad sentiment without distinct topics.
• sentiment_index_0_100: This normalizes the sentiment score to a 0-100 scale, giving you a clearer picture of sentiment strength (68.75 in this case).
• direction: Shows whether sentiment is rising or falling—in this instance, it's rising.
• region: Specifies the geographical focus of the sentiment—global in this case.

Three Use Cases

Once you have this data, the possibilities are endless:

1. Algo Alert: Set up alerts in your trading algorithms when the sentiment score exceeds a certain threshold (e.g., above 0.5). This could signal a good time to invest in green technologies.

2. Slack Bot: Create a Slack bot that posts daily updates about environmental sentiment. This can keep your team informed without them having to dig through reports.

3. Dashboard: Visualize sentiment trends over time on a dashboard. Use libraries like Dash or Streamlit to create interactive visualizations that give you insights at a glance.
