Elasticsearch API (cat indices) to get only user created indices

Hi Support Team,

How can i write the cat indices API (or any if there is an alternative) to get the list of user created indices.

Using cat indices API i am getting all the system created indices as well which i want to avoid.

Below is the get call i use to get the indices;
