The Real-Time Stock Market API is an advanced Python project that solves a real-world problem using FastAPI application and Auth middleware, orchestrated with Python 3.11+. It is architected as a modular system where data handling, processing logic, and presentation layers stay cleanly separated, so each part can be developed, tested, and reused independently. The result is a production-grade application that is easy to explain, extend, and present as a final year capstone.
Most existing approaches to this problem rely on manual effort or fragile scripts that are slow, hard to maintain, and unable to scale with growing data. Without an automated, well-structured solution built on Auth middleware, organizations and students alike struggle to get consistent, reliable results, and there is no easy way to monitor, audit, or improve the process over time.
This project builds an automated, modular system that ingests inputs through FastAPI application, processes them with Python 3.11+, and exposes results through Rate limiting. The design emphasizes maintainability, testability, and reusability, so the same architecture can be adapted to related problems with minimal changes. It delivers consistent results, keeps a clear audit trail, and drastically reduces the manual effort involved.
Python 3.11+
Pydantic validation
Object-oriented Python architecture
Typing, logging, and error handling
Config-driven settings
Unit tests with pytest
FastAPI
Modular pipeline built around FastAPI application and Auth middleware
Configurable thresholds and parameters via settings files
Comprehensive logging and error handling
Well-documented public interface for reuse
Automated tests covering critical paths
Clean separation of data, logic, and presentation
The system follows a layered architecture. The data layer handles acquisition and cleaning through FastAPI application; the logic layer implements the core processing with Python 3.11+ and Auth middleware; and the presentation layer exposes results through Rate limiting. A shared configuration module and a logging module support all layers, while the whole system is wrapped with automated tests. This separation makes the project easy to debug, benchmark, and extend.
