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

In the world of music, sentiment can shift rapidly based on trends, releases, and public perception. Tracking these changes can be a daunting task if you’re trying to scrape data from various sources manually. That's where the Pulsebit API comes into play, providing a straightforward solution to detect sentiment shifts in music using just one endpoint.

The Problem (DIY scraping pain)

As developers, we often face the challenge of scraping data from multiple websites to track sentiment. This can be time-consuming and usually involves dealing with inconsistent HTML structures, rate limiting, and CAPTCHA challenges. Plus, if you're not careful, you could end up violating terms of service.

For example, if you wanted to monitor how sentiments around a new album release are evolving, you'd likely need to fetch data from forums, social media, and streaming platforms. This DIY approach can quickly turn into a nightmare of maintenance and troubleshooting.

The Solution (Pulsebit API — one endpoint)

Enter the Pulsebit API. This powerful API simplifies the process of tracking sentiment shifts by offering a single endpoint to access music sentiment data. Instead of scraping, you can send a simple GET request and receive structured data back.

The endpoint we’ll use is /news_semantic, designed to return sentiment analysis on music-related news articles, providing insights into the public's feelings toward specific tracks or albums.

The Code (Python GET /news_semantic)

Here’s how you can use the Pulsebit API to fetch sentiment data using Python.

First, install the necessary libraries if you haven’t already:

pip install requests

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

import requests

# Define the endpoint and parameters
url = "https://api.pulsebit.co/v1/news_semantic"
params = {
    "query": "latest music news",
    "language": "en"
}

# Send the GET request
response = requests.get(url, params=params)

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

This script sends a request to the Pulsebit API and prints the resulting JSON data.

Reading the Response

Now let's break down the response you might receive:

• music sentiment: The overall sentiment score, which indicates the public’s emotional response to music. For example, the current sentiment is +0.00, suggesting neutrality.

• momentum: This score tells you how quickly sentiments are changing over time. A momentum of +0.70 indicates a positive shift in sentiment, which could be critical for timing market actions.

• clusters: This field indicates how many distinct sentiment clusters were identified in the data. A 0 here means that there wasn't enough variation in the data to create clusters.

• confidence: This score (here, 0.87) represents the API's confidence in its sentiment analysis. A higher number means you can trust the sentiment score more.

Three Use Cases

1. Algo Alert: You can set up an algorithmic trading alert based on sentiment shifts. For instance, if the momentum exceeds a certain threshold, your algorithm could trigger buy/sell actions on relevant music stocks or NFTs.

2. Slack Bot: Create a Slack bot that posts sentiment updates in a channel. You can fetch data every hour and send alerts if sentiment changes significantly, keeping your team informed in real-time.

3. Dashboard: Build a real-time dashboard that visualizes sentiment trends using libraries like Plotly or Matplotlib. This can help music labels or artists understand how their releases are being received.
