## Response Fields

`summary.actual` and `summary.compare` include total, responded, and unanswered counts and rates. `dataPoints` contains the same metrics for each time bucket. `groupByType` identifies the bucket size, and `dataPresent` indicates whether the period contains data.

## Notes

* Both comparison dates must be provided for comparison data to be applied. When neither is supplied, `summary` and each `dataPoints` entry contain only `actual` — no `compare` key at all.
* When `startDate`/`endDate` are both omitted, the live API does **not** default to 3 months back — it returned full account history (`dateDiff` of 13,000+ days) grouped by year in testing. Pass explicit dates for a bounded window.
