Profiles & Backlinks

These endpoints surface derived social data from Constellation, the external graph service. Both are best-effort: counts default to zero when Constellation is not configured or unavailable.

GET /profiles/{did}/summary

Social summary for an actor: follower count via Constellation.

Best-effort — if Constellation is unavailable follower_count is 0 rather than an error.
