How do I know if I have V3?

I just received a message from Rapid API (below). It says that I have to upgrade to V3. How do I know the version I am using at rowdie.co.uk?

here the msg.

We want to remind you that the V2 (https://www.api-football.com/documentation) of our API, deprecated for the past 2 years, will be removed from RapidAPI as of April 30. To ensure uninterrupted access, please migrate to V3 (https://www.api-football.com/documentation-v3) as soon as possible.
