Are you looking out for following kind of information's to get via Ambari APIs (Which we see in the Ambari YARN Summary Page) ?

.Submitted Apps:

http://erie1.example.com:8080/api/v1/clusters/ErieCluster/host_components?HostRoles/component_name=R...

. Pending Apps

http://erie1.example.com:8080/api/v1/clusters/ErieCluster/host_components?HostRoles/component_name=R...

.Running Apps

http://erie1.example.com:8080/api/v1/clusters/ErieCluster/host_components?HostRoles/component_name=R...

Here "erie1.example.com" is ambari server hostname.

Similarly you can get the Completed/Killed/Failed application informations.

Apart from Ambari API, If you are open for other API options then you might want to take a look at the Resource Manager Rest APIs as well:

https://hadoop.apache.org/docs/r2.7.2/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html
