```


Runs a specific Actor and returns its output. The run must finish in 300 seconds otherwise the API endpoint returns a timeout error. The Actor is not passed any input.

Beware that it might be impossible to maintain an idle HTTP connection for a long period of time, due to client timeout or network conditions. Make sure your HTTP client is configured to have a long enough connection timeout. If the connection breaks, you will not receive any information about the run and its status.

To run the Actor asynchronously, use the  API endpoint instead.
