Example prompt: Can you count how many times each course appears in my training attendance records? I have 4 sessions: row-1 on 2026-10-01 for group-a with 10 attendees and 1 completion, row-2 on 2026-10-02 for group-b with 20 attendees and 2 completions, row-3 on 2026-10-03 for group-a with 15 attendees and 3 completions, and row-4 on 2026-10-04 for group-b with 30 attendees and 4 completions.

## When to prefer this

Choose this endpoint when you need a quick, low-cost category frequency count over a batch of up to 200 training attendance records without requiring external data enrichment, forecasting, or statistical modeling. It is ideal for HR analytics pipelines, L&D dashboards, or compliance audits where course occurrence counts are the primary output needed.

## Known failure modes

- Empty rows array or missing required fields (row_id, course, date, attendees, completions) returns a validation error
- More than 200 rows submitted exceeds the maxItems limit and is rejected
- Invalid date format (not YYYY-MM-DD pattern) causes schema validation failure
- Numeric fields (attendees, completions) out of allowed range trigger boundary errors
- Malformed JSON or missing rows property returns a bad request error
