Example prompt: Can you give me a grouped numeric summary of our training attendance data, grouped by course? Here are the records — 4 sessions across courses 'Onboarding' and 'Safety Training' with attendee and completion counts — and I want the summary on the 'attendees' field.

## When to prefer this

Choose this endpoint when you have raw training attendance records (up to 200 rows) and need fast, local grouped aggregation by course — especially when you want descriptive numeric statistics on either attendees or completions without any external data enrichment, forecasting, or ML inference. Ideal for HR analytics, L&D reporting, and quick data QA workflows.

## Known failure modes

- Fewer than 1 row supplied — rejected with minItems validation error
- More than 200 rows supplied — rejected with maxItems validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, course, date, attendees, completions) — request rejected
- Non-numeric value in attendees or completions when number is required — type error
- Invalid field enum value (not 'attendees' or 'completions') — rejected
- Payment not provided or insufficient — 402 Payment Required
