1.  Request

GET / POSThttps://imagerecognize.com/api/v3/
GET / POSTapikeystringYes
GET / POSTtypestringYes
POSTmax_labelsint > 0If ‘type’ is ‘objects’
POSTmin_confidence0 <= int <= 100If ‘type’ is ‘objects’
POSTnsfw_min_confidence0 <= int <= 100If ‘type’ is ‘nsfw’


The apikey is used to validate the request source and must be sent with all client requests. GET request is only allowed together with type ‘cache’.


The type is used to identify which part of the recognition engine to use. It must be one of the following string values:

POSTobjectsIdentify objects using the Object Recognizer
POSTcelebritiesIdentify celebrities using the Celebrities Recognizer
POSTdetect_facesDetect and identify faces using Face Recognizer
POSTdetect_textExtract text using Text Recognizer
POSTnsfwDetect unsafe and NSFW content using NSFW Recognizer
GET / POSTcacheRetrieve cached results from previous API calls


The file is the image which is to be analyzed. The image must be in PNG, JPG or JPEG format.


The max_labels parameter is used to set the maximum number of detected objects in the response. This parameter is used only for type ‘objects’.


The min_confidence parameter is used to set a lower threshold of confidence detection. In general, a lower number returns more objects. This parameter is used only for type ‘objects’.


The nsfw_min_confidence parameter is similar to the min_confidence parameter, but used for the type ‘nsfw’ instead.

d = {'apikey': API_KEY,
     'type': 'objects',
     'max_labels': 10,
     'min_confidence': 80}

r = requests.post(url=API_ENDPOINT, data=d, files=f)
