SHA256 sum of cask without installation

[guadagn0]

Is there a way to obtain the SHA256 sum of a given homebrew cask, without installing such cask?

I'm asking because I installed a specific application (https://www.irradiatedsoftware.com/sizeup/) directly from their website, which however doesn't offer a way to verify the integrity of the download. Only afterwards I realized that the same application was available as homebrew cask.

Thank you. (Homebrew is amazing.)

There is brew fetch sizeup to download and print the shasum, brew info sizeup --json=v2 or brew cat sizeup and the info data is also available at https://formulae.brew.sh/api/cask/sizeup.json.
