I am working on a Plugin. I am using Settings API like below.

register_setting( 'sports_api_key', 'sports_api_key' );

How can I sanitize settings API Text value here ?

Add a third parameter, which is an $args array, and add your sanitization callback in there:

        'sanitization_callback' => 'sanitize_text_field'

This is enough for your use case, the sanitize_text_field function already exists, so you don't need to create it.
