How to fetch a version predicted, optimistic, and pessimistic completion dates via JIRA API?

[João Bertacchi]

I want to create a Dashboard for all my projects showing the following information for each project version:

• version name
• a chart bar showing the number (or story points) of closed issues and the total number (or story points) of issues
• start date
• planned end date (release)
• predicted completion date
• pessimistic completion date
• optimistic completion date

obs: Above info should be displayed twice (once for each version) for a project with two version.

I noticed that Version Report (https://confluence.atlassian.com/jirasoftwarecloud/version-report-777001521.html) contains all information that I need.

Is there a pre-built gadget that contains all that information?

I also consider building my own gadget. However I couldn't find an API for fetching a version predicted, optimistic, and pessimistic completion dates. What API can I use to fetch them?
