Help with API syntax

I’m trying to determine the correct HTTP syntax for the SearchRequest API to retrieve all requests in Blackbaud Grantmaking. If this isn't possible, I’d at least like to extract all requests where disposition = "Approved".

For context, here’s an example of what I mean by HTTP syntax:
To retrieve all information for organization ID = 2250, I would use the GetOrganization API with the following syntax:

    https://api.sky.blackbaud.com/grantmaking/api/v1/organizations/2250

What would be the equivalent URL for extracting all requests using the SearchRequest API?

Any guidance you can provide would be greatly appreciated.
