Finally these too commands saved the day
First use swift and change access control of container
swift post container-name --read-acl ".r:*,.rlistings"
Next Using Curl Configure Container to a particular Url for accessing Files
curl -X GET " https://<access point>/<version>/AUTH_projectID/container-name" -H "X-Auth-Token:<auth token>" -H "X-Container-Read: .r:*,.rlistings"
And also very grateful for the help provided by Alex da Silva
