Personally, I don't have a project that requires it right now, but aspirationally maybe! I agree with another commenter that mentioned this is basically a public service that should exist similar to Wikidata / Musicbrainz.

I know this is currently a paid service you're trying to make happen and the scraping part is a reasonable amount of effort, but if you wanted to make the data source public, you could publish community.lexicon.calendar.event ATProto records and it would be very cool. At the very least, you could ingest it as a data source!

x2 for Toronto.

There's hundreds of events happening every week but finding them takes a lot of time.
