getting amount off reco's via json

Hello i get successfully the  rating off my  uploaded image in the clouddatabase via json.

Dump => object(stdClass)#22 (4) {
  ["result_code"] => string(7) "Success"
  ["transaction_id"] => string(32) "32c8ff00538ff4817b663705771d7bd5a"
  ["target_record"] => object(stdClass)#24 (6) {
    ["target_id"] => string(32) "ed2af9020e4849b7ad1e1fcb561b6a02"
    ["active_flag"] => bool(true)
    ["name"] => string(20) "B2ZsP_20150929135251"
    ["width"] => float(640)
    ["tracking_rating"] => int(5)
    ["reco_rating"] => string(0) ""
  }
  ["status"] => string(7) "success"
}

How do i retrieve the amount  off times a target is recognized (recos)? Do i miss something?
