you should cache api responses when you need to speed up your apps and reduce the load on your server it helps a lot

hey folks, i've been thinking a lot about api performance recently. we're seeing some endpoints struggle under load, and caching seems like the obvious next step. but what's the general rule of thumb? is it purely about request volume, or are there other factors like data volatility or complexity of generating the response that should push us towards caching? curious to hear what triggers your caching decisions.
