How it works
Three steps from agent question to sourced answer.
01 — ASK
Your agent calls Sonar as a tool
Your agent passes a question — a topic, event, or speaker — as a tool call in its loop.
audio.search({ query: "What are lawmakers saying about grid storage?" })
02 — FIND
Sonar searches public audio
News, podcasts, radio, earnings calls, social audio, and archives — ranked clips with accurate transcripts, timestamps, and speaker attribution.
audio.search(query) → ranked clips
03 — CITE
Results your agent can act on
Each hit includes an accurate transcript, timestamp, speaker, and source — ready for your agent to quote or summarize.
{ source, speaker, ts, transcript }
