## Example

This API retrieves prompts from images.

Please set the **`Content-Type`** header to **`application/json`** in your HTTP request to indicate that you are sending JSON data. Currently, **only JSON format is supported**.

`Request:`

```bash theme={"system"}
curl --location 'https://api.novita.ai/v3/img2prompt' \
--header 'Authorization: Bearer {{API Key}}' \
--header 'Content-Type: application/json' \
--data '{
    "image_file": "{{Base64 encoded image}}"
}'
```

HTTP status codes in the 2xx range indicate that the request has been successfully accepted. A status code of 400 means there is an error with the request parameters, while status codes in the 5xx range indicate internal server errors.

You can find the generated prompt in the `prompt` field of the response.

`Image`:

  <img src="https://next-app-static.s3.ap-southeast-1.amazonaws.com/get-started/img2prompt.png" />
</Frame>
