Get Classify Run

Retrieve details about a specific classify run, including its status and outputs.

A common use case for this endpoint is to poll for the status and final output of a classify run when using the Create Classify Run endpoint. For instance, if you do not want to not configure webhooks to receive the output via completion/failure events.
