Add docstrings #6
Description
It would be good to write some docstrings to describe public methods in api.py file.
Docstrings should be in format:
"""Short description.
Longer description
if needed.
Args:
param1 (int): The first parameter.
param2 (str): The second parameter.
Returns:
int: Sum of param1 and length of param2.
Raises:
ValueError: If arguments have wrong types.
