# Get Entity Evidence

> Returns the best verbatim customer-call quotes evidencing a library entity, with speaker attribution, call context, and recording time anchors. Prefers moments the analytics pipeline explicitly linked to the entity; falls back to semantic search. Use to back up a persona pain, competitor claim, objection, or proof point with real customer language.
