List All Organizations

Every organization on the platform, with its plan and its apps' tiers.

GET /api/orgs deliberately returns only orgs the caller BELONGS to, even for a super admin — membership is how that endpoint authorizes, and widening it would change what it means for everyone. So the admin view is its own endpoint rather than a flag on that one, and this is the list the admin screens pick an organization from instead of asking someone to type a slug.
