Example prompt: Can you group my water monitoring records by site and give me a summary of the litres field? I have 4 records: row-1 at group-a on 2026-10-01 with 10 litres and cost 1, row-2 at group-b on 2026-10-02 with 20 litres and cost 2, row-3 at group-a on 2026-10-03 with 15 litres and cost 3, and row-4 at group-b on 2026-10-04 with 30 litres and cost 4.

## When to prefer this

Choose this endpoint when you need fast, local grouped aggregate statistics for water monitoring data (litres or cost) segmented by site, with up to 200 records, and no need for external data enrichment, forecasting, or geospatial analysis. Ideal for utility dashboards, cost audits, and consumption comparisons across sites.

## Known failure modes

- Fewer than 1 row supplied — returns validation error
- More than 200 rows supplied — request rejected with maxItems error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, site, date, litres, cost) — request rejected
- Invalid field enum value (not 'litres' or 'cost') — validation error
- Null values in the selected numeric field may affect aggregate accuracy
