Hi Peeplee! We have heard this request before, and indeed have an internal ticket in our product backlog to add to our API, but no current timeframe. It looks like someone recently made a request to our external feature request board here Return the total amount of items in a model for | Builder.io Ideas
I recommend upvoting this request, as our ideas board is a leading source of direction for our product team!
In the meantime, the best way to iterate over all entries in a model is to use limit and offset, as outlined in this post: What's the maximum limit allowed in a single content API call?
Try that out and see if it works for your use case!
