+===========================================
+Data Types
+===========================================
+
+The Data Types module defines structured data models used throughout
+the PaystackEase library when sending requests to the Paystack API.
+
+These models are implemented using **Pydantic**, which provides automatic
+data validation and type checking before data is sent to the API.
+
+Using these models ensures that required fields are provided and that
+data types are correct.
+
+
+Bulk Charge Data Models
+-----------------------
+
+These models are used when interacting with the Bulk Charges API.
