The search queries an AI generates behind the scenes when answering a prompt. Coverage is partial: metrics cover only runs that emitted fanout data (see info.coverage_note).

• Metrics: total_fanouts (query count), fanouts_per_execution (avg queries per execution), query_variations (distinct fanout queries), share.
• group_by: prompt (default), query, model, region, date.
• query requires prompt in group_by; share requires query; query_variations can’t be combined with query.
• analysis_type filter defaults to visibility.

Streaming (SSE) variant (same body, /stream)

POST /v2/reports/query-fanouts/stream takes the same request body and returns Server-Sent Events: one summary event (the info block), then one result event per row. limit/cursor are ignored; it returns everything by default. Pass max_results to cap.

Response (text/event-stream)

event: summary
data: { ...the info block... }

event: result    ← one per row, same shape as data[] above
data: {"prompt": "AI search optimization startups...", "rank": 1, "total_fanouts": 190, "fanouts_per_execution": 3.0, "query_variations": 143}
