Is it possible to cache the return of a server action until the next build?

I have a data source I can barely do 20 requests per day because it's complex and expensive. I want to fetch my whole data source at build time, only once and cache it until the next build process. Would it be possible to do so?
I want to use this cached server action in another endpoint, where I can filter and sort the data without spamming the original data source.

Or make use of TTL cache and set the cache time to infinity.
So the data are fetched on demand (so that the build time won't get super long just to wait for the data) but is cache forever.
E.g. https://www.npmjs.com/package/@isaacs/ttlcache

here is couple way to run some pre-build script https://github.com/vercel/next.js/discussions/17479 you can make script to download data from your api and then fetch it from local file instead remote api

That's a nice idea as well. Thank you.

Can I mark both as solutions?
You can only mark one, so yeah you have to choose the one that is more helpful to you. Don’t worry, people won’t mind if you select someone else’s answer

Thanks, I will mark the one that works better to me once I test them.
