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

In the world of agriculture, understanding market sentiment can significantly impact decision-making. However, gathering and analyzing this data can be a daunting task. Let's dive into how you can efficiently detect sentiment shifts using the Pulsebit API.

The Problem (DIY scraping pain)

If you've ever attempted to scrape data from news websites or social media platforms to gauge agriculture sentiment, you know it can quickly become a headache. You have to deal with different HTML structures, rate limiting, and often, the risk of getting your IP blocked. Plus, maintaining all that code over time can be a real pain.

The Solution (Pulsebit API — one endpoint)

Enter the Pulsebit API. With a single endpoint, you can pull sentiment data without the hassle of scraping. This API aggregates news articles, analyzes sentiment, and provides you with structured data that's easy to work with. For agriculture, Pulsebit provides a robust way to capture sentiment shifts in real-time.

The Code (Python GET /news_semantic with code blocks)

Here's how to get started using the Pulsebit API in Python. First, ensure you have the requests library installed. If you haven't installed it yet, you can do this using pip:

pip install requests

Now, you can use the following Python code to hit the /news_semantic endpoint:

import requests

def get_agriculture_sentiment(api_key):
    url = 'https://api.pulsebit.co/news_semantic'
    headers = {
        'Authorization': f'Bearer {api_key}',
        'Content-Type': 'application/json'
    }
    params = {
        'category': 'agriculture'
    }

    response = requests.get(url, headers=headers, params=params)

    if response.status_code == 200:
        return response.json()
    else:
        print(f"Error: {response.status_code} - {response.text}")
        return None

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

Reading the Response

When you call the /news_semantic endpoint, you will receive a JSON response similar to this:

{
  "sentiment": 0.00,
  "momentum": 0.80,
  "clusters": 0,
  "confidence": 0.87
}

Here's a breakdown of each field:

• sentiment: A score that indicates the overall sentiment in the agriculture sector. A value of 0.00 indicates neutral sentiment, while positive values indicate bullish sentiment and negative values indicate bearish sentiment.

• momentum: A measure of the rate of change in sentiment. A momentum score of 0.80 suggests a strong upward trend, indicating that sentiment may be shifting positively.

• clusters: This field indicates the number of distinct sentiment clusters identified in the news articles analyzed. A value of 0 means no significant clusters were detected.

• confidence: A score between 0 and 1 that reflects how confident the API is in its sentiment analysis. A confidence level of 0.87 suggests a high degree of certainty in the analysis.

Three Use Cases

1. Algo Alert: Set up an algorithmic trading alert that triggers when sentiment shifts beyond a certain threshold. For instance, if momentum exceeds 0.75, you could execute a buy order for agricultural stocks.

2. Slack Bot: Integrate the API with a Slack bot that sends daily updates on agriculture sentiment. This can keep your team informed of market changes in real-time.

3. Dashboard: Build a simple dashboard using a library like Dash or Streamlit to visualize sentiment changes over time. This can help in making informed decisions based on trend analysis.
