Rest API endpoint to fetch logs for a pipelinerun 

Hi, 
I'm currently working on integrating Tekton with our current app. I was looking to fetch logs for the pipelinerun via a rest api instead of individually fetching all the  pods corresponding to each task and pulling the logs for each. 

Is there any rest api to do exactly what the tekton cli does - 
tkn pipelinerun logs -L  tekton-pipelinerun-test-task-8v826
