Can use rest api to fetch cloud list?

i use “/computer/api/json” to get node list. I thought cloud list had the same api, but not.
Here is my attempt:
/cloud/ → html response, is web page
/cloud/api/json → 404 not found
/cloud/api/xml-> 404 not found

jenkins 2.426.2

has any way?

We have no REST API in Jenkins. Every Remote API needs to be enabled by hand. You see all available API endpoints by clicking on the REST API button of a model object in the bottom right corner in the Jenkins UI. Typically this button is bound to the URL /cloud/api if available.
