Return aggregated raw sensor points for one signal. Samples are bucketed before they are returned. The bucket width is `agg_period` x `agg_unit` (`agg_period=15`, `agg_unit=m` is a 15-minute bucket) and `agg_function` is how samples inside a bucket are reduced. By default points are returned as a `data` list of `{timestamp, value}` objects. Pass `transpose=true` to get two arrays of equal length instead, `timestamps` and `values`, where `values[i]` belongs to `timestamps[i]`. It carries the same points in a smaller body. Two limits are enforced and both reject the request rather than truncating the response: the window between `start_time` and `end_time` may not exceed **14 days**, and a query may not produce more than **10,000 points**. The defaults (`agg_unit=s`, `agg_period=1`) reach the point ceiling after under three hours, so most callers set them explicitly.
