Authorization Key is not working

My API key is not working from a week. I regenerate new key still its not working. I am using this service from 3 years. Using this as endpoint “” for using new and existing key getting no result, there is no error generated.

How can I know my key is valid or not and how many days it will take to activate new key?

Hello Team
