   • Upon successful authentication, users receive a JWT token, granting access to protected endpoints in other microservices.

2. Stock Information and Watchlist Management:

   • The Stock Info Microservice provides real-time stock information, including detailed data and search functionality.
   • Watchlist-related operations, such as adding, removing, and retrieving symbols, are handled by the Authentication Microservice.

3. News Article Retrieval:

   • The News Service fetches stock-related news articles from external sources.
   • The Sentiment Analysis Microservice utilizes these articles for sentiment analysis.

4. Sentiment Analysis Integration:

   • The Sentiment Analysis Microservice performs real-time sentiment analysis on specific stocks.
   • It seamlessly integrates with the Authentication Microservice to ensure authenticated access to its sentiment analysis endpoint.

Seamless User Experience

The interplay between these microservices ensures a cohesive and responsive user experience. Users can seamlessly register, authenticate, access real-time stock information, manage their watchlist, and receive sentiment analysis—all within the Arbitra Pulse API ecosystem. Each microservice plays a vital role, contributing to the comprehensive functionality of the entire system.

Technology Stack

The Arbitra Pulse API leverages the following technology stack:

• Node.js: Runtime environment for server-side applications.
• Express.js: Minimal and flexible Node.js web application framework.
