I have a question about #activitypub.

Is there a straight forward way like an API or a lib to extract all the people who boosted a certain toot within a specific time window?

My naive approach without knowledge about activitypub would be to parse the html from the /boost endpoint to get the users and then look at their timeline for the toot.

But I am quite sure there must be an easier way. And maybe you can help me by pointing in the right direction.
