Querying manifest data

Is it possible to query the data contained in snap/manifest.yaml from the store API without downloading the snap package?

I would like adjust my nightly builds setup to ensure the snap package only gets rebuild if there are new commits. It would be awesome if there was some way to extract this information by looking up the source-commit in snap/manifest.yaml for the given part - ideally without having to download the snap first.

At the moment I’m using the version field obtained by querying the store API but getting the complete hash from manifest.yaml would be preferable.

Is there a better way to do this? Thanks!
