Detecting Safe Search Properties

Safe Search Detection detects explicit content such as adult content or violent content within an image. This feature uses five categories ("adult", "spoof", "medical", "violence", and "racy") and returns the likelihood that each is present in a given image. See the SafeSearchAnnotation page for details on these fields.

Running Safe Search Detection on a local image

Protocol

Refer to the images:annotate API endpoint for complete details.

To perform Safe Search Detection, make a POST request and provide the appropriate request body:

POST https://vision.googleapis.com/v1/images:annotate?key=YOUR_API_KEY

{
  "requests": [
    {
      "image": {
        "content": "/9j/7QBEUGhvdG9zaG9...base64-encoded-image-content...fXNWzvDEeYxxxzj/Coa6Bax//Z"
      },
      "features": [
        {
          "type": "SAFE_SEARCH_DETECTION"
        }
      ]
    }
  ]
}

See the AnnotateImageRequest reference documentation for more information on configuring the request body.

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

{
  "responses": [
    {
      "safeSearchAnnotation": {
        "adult": "VERY_UNLIKELY",
        "spoof": "VERY_LIKELY",
        "medical": "UNLIKELY",
        "violence": "UNLIKELY",
        "racy": "VERY_UNLIKELY",
      }
    }

Running Safe Search Detection on a Remote Image

For your convenience, the Vision can perform Safe Search Detection directly on an image file located in Google Cloud Storage or on the Web without the need to send the contents of the image file in the body of your request.

Protocol

Refer to the images:annotate API endpoint for complete details.

To perform Safe Search Detection, make a POST request and provide the appropriate request body:

POST https://vision.googleapis.com/v1/images:annotate?key=YOUR_API_KEY

{
  "requests": [
    {
      "image": {
        "source": {
          "gcsImageUri": "gs://YOUR_BUCKET_NAME/YOUR_FILE_NAME"
        }
      },
      "features": [
        {
          "type": "SAFE_SEARCH_DETECTION"
        }
      ]
    }
  ]
}

See the AnnotateImageRequest reference documentation for more information on configuring the request body.

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

{
  "responses": [
    {
      "safeSearchAnnotation": {
        "adult": "VERY_UNLIKELY",
        "spoof": "VERY_LIKELY",
        "medical": "UNLIKELY",
