# Workspace and Project IDs

Retrieve workspace and project IDs for use with the API.

To run inference on your model, or to query the Roboflow API endpoints associated with your project, you will need three pieces of information:

1. Your project ID
2. Your model version number
3. [Your API key](https://app.roboflow.com/settings/api)

### How to Retrieve a Project ID and Version Number

To get both the project ID and version number, navigate to "Models" page inside your Project. It will list all fine-tuned models, and each one contains the ID that you can easily copy:

In the screenshot above, the `dino-game-rcopt-fjzyh` is the Project Id, and the numbers after the `/` are the model version numbers.
