oes Microsoft Project's API allow extracting project data without a full license?

Question

Hello Microsoft Team,

I’m evaluating Microsoft Project for my organization and need to confirm if its API supports our use case before purchasing a license.

Our Goal: We want to extract project data (tasks, timelines, resources) programmatically via API to integrate with our internal systems.

Questions:

Is there a way to test the API (e.g., with a trial license) before buying a full subscription?

Does the API allow read-only access to project data (e.g., via REST or Graph API)?

Are there limitations on data extraction depending on the license type (Project Plan 3 vs. 5)?

We want to ensure the API meets our needs before committing. Any guidance or documentation references would be greatly appreciated!
