API Rate Limiter

[JacobLinCool]

I would like to implement a rate limiter based on the time usage of actions.

In a time interval (maybe 15 minutes):

• Every user has 500 ms credits.
• If a user has a verified trait, then it gets 2000 ms extra credits.
• If a user has other traits, it may get extra credits.

In the above scenario, we can serve around 300 users at once:

$(15 \times 60) \div (0.5 + 2) = 360 \Rightarrow 300$ (We need some resources to do checks and other chores)

Since we do not have extra machines to do scaling and we haven't thought about it, a rate limiter would be necessary.

I do believe that we can scale, but more research must be done.

Feel free to discuss the topic, thanks.
