**How to obtain your API Key**To obtain your API key, follow these simple steps:

  1. **Create a user profile and log in to the platform**

    If you don't have an account yet, visit our platform and create a user profile. Once you've completed registration and verified your email, log in with your credentials.

  2. **Access the user menu**

    After logging in, click on your name or the user icon in the top-right corner of the screen.

  3. **Select the API Key option**

    In the dropdown menu that appears, select the "API Key" option. From there, you can view or generate your API key.
Now you are ready to use your API key in our API!
**How to use the API**To use the API, first make a **POST** request to start the classification. Then, use the provided ***identifier*** from the **POST** request to retrieve the results.
**1. Image Classification** * To classify an image, you need to make a **POST** request to `/api/classification` with the required parameters (for details on the parameters, refer to the *"Classification"* section below). * In the response, you will receive the ***identifier*** of the classified image. * Use the provided ***identifier*** to retrieve the classification results by making a **GET** request to `/api/classification/{identifier}` (for details on how to structure this request, see the *"Classification"* section below). * The response will contain the classification results for the image in JSON format.
In the response, you will find a ***results*** array, which includes the classification results for each model used, and a ***verdicts*** array, which contains the results for each heuristic applied.
If the classification is not yet complete, continue sending the **GET** request until the result is available.
**2. Video Classification** * To classify a video, you need to make a **POST** request to `/api/classification_video` with the required parameters (for details on the parameters, refer to the *"Classification"* section below). * In the response, you will receive the ***identifier*** of the classified video. * Use the provided ***identifier*** to retrieve the classification results by making a **GET** request to `/api/classification_video/{identifier}` (for details on how to structure this request, see the *"Classification"* section below). * The response will provide the classification results for the video in JSON format. For video classification, the video is divided into *frames*.
In the response, you will find a ***results*** array that includes the classification outcomes for each model applied to each analyzed frame, and a ***verdicts*** array containing the results for each heuristic used.
If the classification is not complete, continue sending the **GET** request until the final results are returned.
**3. All Classifications**The `/api/classifications` endpoint will return all the image classifications made by a user. This will list the results of all past image classification requests.
**4. User Management** The **POST** `/api/user` endpoint allows you to create a user, while the **DELETE** `/api/user` endpoint is used to delete a user (For the structure of the requests, see more in the user section below).

Otherwise, the result can be obtained by polling the [relative endpoint](./get-classification-result-speech). Please note that in order to use a webhook callback URL **you need to request a specific enablement**, otherwise the parameter is ignored. Moreover, the system may cache the analysis results of repeated submissions, i.e. submissions of the same file with the same options: in this case the webhook won't be called and the results would be accessible only by polling the [relative endpoint](./get-classification-result-speech). no_cache: type: boolean description: >- Set it to true to force the system to reprocess the image even if it has been previously submitted with the same options.
