Do you have an RDP account?
If so, you would have received a "Welcome" email which contains a Machine Account / Machine ID - which looks something like this: GE-A-xxxxxx-x-xxx
Also, assuming you followed the registration steps in the above Welcome email, you should be able to log into our API Playground - https://apidocs.refinitiv.com/Apps/ApiDocs - using your corporate email address.
From there you can search for the Estimates API - /data/estimates/v1/ which has various estimates related APIs e.g. /data/estimates/v1/view-summary/annual
You can test out the various APIs in the Playground - as well as access documentation under the Reference tab.
Once you have identified the correct APIs that meet you requirements, you can then use Python scripts to access that data using the HTTP Restful interface offered by RDP - which you can learn more about at Refinitiv Data Platform APIs | Refinitiv Developers and Tutorials | Refinitiv Developers
