for getting the version on the index you can use the following curl

curl -XGET {host}:{port}/{index}/_settings?pretty

your required information will be in "version" key, for my index which was created with ES 6.5 -

"version" : {
          "created" : "6050499"
        }

for getting information on all the indices you can drop the {index} part and your curl would look like -

curl -XGET {host}:{port}/_settings?pretty
