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

The Problem

In the world of trading, timely insights are critical. Keeping an eye on market sentiments can make or break your strategy, especially in the commodities sector. Unfortunately, traditional methods of gathering sentiment data often involve tedious web scraping, which can be error-prone and time-consuming. Moreover, scraping has its own set of risks, including rate limits and the potential for breaking changes to website structures.

If you're looking for a more reliable and efficient way to get sentiment data, you're in luck. The Pulsebit API provides a straightforward solution that taps into sentiment analysis without the hassle of DIY scraping.

The Solution

The Pulsebit API is designed to simplify the process of gathering sentiment data. With just one endpoint, you can access a wealth of information about market sentiment and momentum. This API is especially useful for commodities traders who need to respond quickly to shifts in market sentiment.

Key Features of the Pulsebit API

• Real-Time Data: Get up-to-date sentiment metrics.
• Comprehensive: Analyze various commodities with a single API call.
• User-Friendly: Easy-to-use, well-documented API.

The Code

To get started with the Pulsebit API, you will first need to set up your Python environment. Install the requests library if you haven't already:

pip install requests

Now, you can use the following code snippet to make a GET request to the /news_semantic endpoint:

import requests

def get_commodities_sentiment():
    url = "https://api.pulsebit.co/news_semantic"
    headers = {
        "Authorization": "Bearer YOUR_API_KEY"  # Replace with your actual 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}")

if __name__ == "__main__":
    sentiment_data = get_commodities_sentiment()
    print(sentiment_data)

Replace YOUR_API_KEY with your actual Pulsebit API key. This code makes a GET request to the API and prints the sentiment data.

Reading the Response

When you call the get_commodities_sentiment function, you'll receive a JSON response that includes several key fields. Here’s a breakdown of the relevant fields:

• sentiment: The overall sentiment score for commodities, e.g., +0.00 indicates neutrality.
• momentum: A momentum score, e.g., +0.67, suggests a positive trend.
• clusters: The number of sentiment clusters detected, e.g., 0, indicating no significant clustering.
• confidence: The confidence level of the sentiment data, e.g., 0.87, which suggests a strong reliability.

Three Use Cases

1. Algo Alert: You can set up an algorithmic trading alert that triggers when the sentiment or momentum score exceeds a particular threshold. For example, if the momentum goes above +0.70, it could signal a buying opportunity.

2. Slack Bot: Integrate the sentiment data into a Slack bot that posts updates about commodities sentiment. This way, your team stays informed without needing to check the API manually.

3. Dashboard: Create a dashboard that visualizes sentiment trends over time. You can use libraries like Matplotlib or Plotly to render live sentiment data in a user-friendly format.
