Asterisk ARI and Get recorded/live voice using rest apis

I was going thru the Asterisk Rest API documentation (https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Recordings+REST+API). Saw a couple of interesting APIs for me. Like,

/recordings/stored

/recordings/stored/{recordingName}

/recordings/live/{recordingName}

/playbacks/{playbackId}

I ‘ve enable ARI in asterisk configuration file and now I am getting response for URL – http://localhost:8088/ari/asterisk/info as below.

{

"build": {

"kernel": "4.4.0-71-generic",

"os": "Linux",

"options": "LOADABLE_MODULES, OPTIONAL_API",

"machine": "x86_64",

"date": "2017-04-04 11:28:35 UTC",

"user": "buildd"

},

"system": {

"version": "13.1.0~dfsg-1.1ubuntu4.1",

"entity_id": "00:00:00:00:00:00"

},

"config": {

"name": "",

"default_language": "en",

"setid": {

"user": "",

"group": ""

}

},

"status": {

"startup_time": "2019-02-27T13:47:18.367+0530",

"last_reload_time": "2019-02-28T14:31:42.227+0530"

}

}

But when I try the GET recordings API URL http://localhost:8088/ari/recordings/stored it give the response - {"error":"Allocation failed"}

I have enabled recording in my extensions.conf as below,

exten => 7001,1,Answer()

exten => 7001,2,Monitor(wav,test)

exten => 7001,3,Dial(SIP/7001,60)

exten => 7001,4,Playback(vm-nobodyavail)

exten => 7001,5,VoiceMail(7001@main)

exten => 7001,6,Hangup()

exten => 7002,1,Answer()

exten => 7002,2,Monitor(wav,test1)

exten => 7002,3,Dial(SIP/7002,60)

exten => 7002,4,Playback(vm-nobodyavail)

exten => 7002,5,VoiceMail(7002@main)

exten => 7002,6,Hangup()

I can see the recorded files test-in.wav, test-out.wav, test1.in.wav, test1.out.wav etc

So my question is can I get the APIs /recordings/stored/{recordingName} and /recordings/live/{recordingName} running and so that I can use/playback it from other applications.
