Every AI agent that researches a topic, writes a brief, or synthesises sources needs to know: who actually knows what they're talking about? That's the call Amygdala answers. Before your agent cites a source or quotes an expert, it calls /api/v1/index/ or /api/v1/detail/ to verify authority.
search_authoritiesSearch any topic and get a ranked list of verified experts in that niche.
