Welcome to the Data Retrieval API guide! This tutorial will help you understand how to fetch and work with data using APIs.

📌 Key Concepts

  • API (Application Programming Interface): A set of rules for interacting with web services.
  • Endpoints: Specific URLs where data is retrieved (e.g., /en/learn/tutorials/data_retrieval_api).
  • HTTP Methods: Use GET for retrieving data, POST for submitting data, etc.

🛠️ How to Use

  1. Install Required Tools
    Ensure you have a tool like Postman or curl for testing APIs.

  2. Send a GET Request
    Example: 

    GET /api/data?format=json HTTP/1.1
Host: example.com
    get_request_example

  3. Process the Response

    • JSON format: Use a JSON parser to extract data.
    • XML format: Parse with an XML library.
    • CSV format: Split by commas for analysis.
