Use api_get_test.py with the following command and arguments:

python api_get_test.py $host $token $endpoint '$options'

$host: Hostname or URL for the system running V‑Spark.
$token: Authorization token with the required read or write permissions for the request.
$endpoint: Request endpoint, including any path parameters.
$options: Optional parameters used to further refine the request and results.
