Question about limits for free tier of Kong Cloud (SaaS)

Hello!
I’m a newbie to Kong.

I want to find detailed limits explanation for free tier of Kong Cloud (SaaS):
konghq.com/pricing

For example it is specified 2m requests per month.
Is there a queries per second limit?

Can not find this info in docs section on Kong website

Is there any information about limits?

Can anyone clarify or point to right direction?
