Caching before making a function request

For Workes & Pages, what is the name of the domain?

Not relevant

What is the issue or error you’re encountering

I fear that the number of function requests may be too high

What are the steps to reproduce the issue?

There is a limit of 100k requests daily on functions. I just want to use the function as a reverse proxy to avoid publicly sharing the API key to a data endpoint that I will use on my data science blog. While my blog is pretty small and receives just a thousand hits monthly, I wonder if it would fail if I suddenly got famous for a day. Is it possible to cache the requests aggressively (hourly, for example), so the number of function requests done for each post is up to 24 (way below the 100k limit)

Note: Apparently, this is called durable in netlify lingo.

I’m pretty sure your function will run before the cache.
