I think "JAMstack" is for content, not interactive services. If your 'service' can be reduced to

HTTP GET /something/

I think JAMstack can do it, but if it involves looking something up in a database, writing something into a database, etc. that is out-of-scope.

The A in JAM means API so that means you can use firebase etc. for dynamic content.
