Example Workflows#

"Am I verified?"#

Call verify_identity → returns trust score, SBT status, and attestations.

"Find me someone compatible"#

1. Call search_connections with optional limit
2. Get back compatibility scores + tmp_ids
3. Use tmp_id to call get_profile, get_reputation, or get_newsfeed for more detail

"What's this person like?"#

1. Call get_profile with a tmp_id → interests, topics, preferences
2. Call get_newsfeed with the same tmp_id → their public posts
3. Summarize shared interests and conversation starters

"Is this person trustworthy?"#

1. Call get_reputation → tier and score
2. Call get_social_signals → engagement quality and confidence
3. Flag if low engagement + high confidence (potential red flag)
