Hi, 

Need to find out if I can get historical data?
Have asked Google, but its all BOTS and Zero customer service.

Any ideas

Historical data for CrUX:
1) https://developer.chrome.com/docs/crux/history-api - api access for 40 data points (covers ~10 months), updated weekly
2) https://developer.chrome.com/docs/crux/bigquery - origin granularity data, released once a month going much further back
3) https://developer.chrome.com/docs/crux/vis - visualizes the data from the crux history api
There are also several third party tools for visualization and usually they include historical data (e.g. from the crux history api, or bigquery).
