How do you get the ID of the owner of a lemmy community via the API?

GET /api/v3/community

It'll respond with an object of GetCommunityResponse (https://join-lemmy.org/api/interfaces/GetCommunityResponse.html)

The moderators array will have an array of objects of which moderator is a Person type.

The "top mod" is also the owner, and they'll always be the first entry in the moderators array from /api/v3/community

 javascript

    
const comunityDetails = await fetch('https://intance.xyz/api/v3/community?community_id=12345')

// Not sure what attribute you need for the owner, but here I'm getting their actor_id (https://instance.xyz/u/username)
const owner = communityDetails.moderators[0].moderator.actor_id





  

o0o sorry, missed that bit!
