🧪 Try APIs using Postman & Swagger

🚀 Using Swagger (Recommended)

👉 Open Swagger UI:

Steps:

1. Open the Swagger link above
2. Browse all available APIs
3. Click on any endpoint
4. Click "Try it out"
5. Enter required parameters (if any)
6. Click Execute
7. View response instantly

💡 Tip: Swagger is the easiest way to understand all available APIs and their request/response structure.

📬 Using Postman

Steps:

1. Open Postman
2. Create a new request
3. Select HTTP method (GET/POST/etc.)
4. Enter full API URL
5. Add query params (if required)
6. Click Send
7. View JSON response

🧩 How to Use Endpoints

Step 1: Call GET /api/companies to fetch the list of available companies.

Step 2: From the response, pick a valid company symbol (e.g., AAPL, TSLA).

Step 3: Use that symbol in the summary endpoint:

GET /api/summary/{symbol}

Example:(just for understanding) GET "https://stock-app.com/api/summary/AAPL"

Note:

• Always use a valid symbol from /api/companies
• Invalid symbols may return an error or empty response
