get_crux_history¶
Query weekly CrUX timeseries for a URL or origin.
The tool accepts the same target, form-factor, and metric controls as
get_crux_data, plus:
| Parameter | Type | Required | Default |
|---|---|---|---|
collection_period_count |
integer | No | 25 |
The allowed range is 1 through 40. Each data point is a 28-day rolling aggregation, and adjacent weekly periods overlap.
CrUX may represent an unavailable historical value as "NaN" or null.
The server normalizes both to JSON null.
