# Quantitative Results

When you perform an analysis, the result you get is a number. For biometry, it reflects a chance that the two or more people represented in your media are the same person. For liveness, it shows a chance of deepfake or a spoofing attack: that the person in uploaded media is not a real one. You can get these numbers via API from a JSON response.

1. [Authorize](https://doc.ozforensics.com/oz-knowledge/guides/developer-guide/api/oz-api/use-cases/authentication). 
2. Make a request to the folder or folder list to get a JSON response. Set the `with_analyses` parameter to `true`.
3. For the Biometry analysis, check the response for the `min_confidence` value:

```json
"items": 
 [
  {
   "analyses": 
    [
     {
      "analysis_id": "biometry_analysis_id"
      "folder_id": "some_folder_id", 
      "type": "BIOMETRY", 
      "state": "FINISHED", 
      "results_data": 
       {
        "max_confidence": 0.997926354, 
        "min_confidence": 0.997926354
       }
```

This value is a quantitative result of matching the people on the media uploaded. 

4\. For the Liveness Analysis, seek the `confidence_spoofing` value related to the video you need:

```json
"items": 
 [
  {
   "analyses": 
    [
     {
      "source_media": 
       [
        {
        "media_id": "your_media_id", 
        "media_type": "VIDEO_FOLDER",
        }
       ]
      "results_media": 
       [
        "analysis_id": "liveness_analysis_id",
        "results_data": 
         {
          "confidence_spoofing": 0.55790174
         }
```

This value is a chance that a person is not a real one.

To process a bunch of analysis results, you can parse the appropriate JSON response.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://doc.ozforensics.com/oz-knowledge/guides/developer-guide/api/oz-api/use-cases/quantitative-results.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
