Parameters

To make a call, you need to pass the following parameters. Mandatory parameters are in bold.
ParameterDescriptionAvailable valuesExample
modeThe type of request. It can be a question about a single file or a set of files. For a single text files, Box AI API supports up to 1MB of text representation. If the file size exceeds 1MB, the first 1MB of text representation will be processed. If you want to list multiple files, the limit is 25 files. Box AI handles image documents with a resolution of 1024 x 1024 pixels, with a maximum of 5 images or 5 pages for multi-page images. If the number of image or image pages exceeds 5, the first 5 images or pages will be processed. If you set mode to single_item_qa, the items array can list only one element. Currently Box AI does not support multi-modal requests. If both images and text are sent Box AI will only process the text.single_item_qa, multiple_item_qasingle_item_qa

ai_agentThe AI agent used to override the default agent configuration. You can use this parameter replace the default LLM with a custom one using the model parameter for shorter and longer texts, tweak the base prompt to allow for a more customized user experience, or change an LLM parameter, such as temperature, to make the results more or less creative. Before you use the ai_agent parameter, you can get the default configuration using the GET 2.0/ai_agent_default request. For specific use cases, see the AI model overrides tutorial.

Use cases

​
Ask questions about an item

This example shows how to ask a question about one or more items using the POST ask/ai API. When using this endpoint, remember to specify the mode parameter depending on the number of items you want to supply. 
curl -i -L POST "https://api.box.com/2.0/ai/ask" \
     -H "content-type: application/json" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -d '{
    "mode": "single_item_qa",
    "items": [
        {
            "id": "12345678",
            "type": "file"
        }
    ],
    "prompt": "List the guidelines on creating questions in Box AI for Documents"
}'
The response will be as follows: 
{
    "answer": "The guidelines for working with questions in Box AI for Documents are as follows:\n\n1. Box AI pulls information only from the document loaded in preview.\n2. If questions fall outside the scope of the document, Box AI will inform you that it cannot answer.\n3. Be specific when asking questions; use parameters like numbered lists, brevity, tables, and central themes or key points.\n4. Aim to stay within the scope of the document.\n5. Focus on text-based responses only.",
    "created_at": "2024-11-04T02:30:09.557-08:00",
    "completion_reason": "done"
}

​
Ask questions with content parameter

If you use the content parameter as the source of input for Box AI, it will use it as the primary source. 
curl -i -L POST "https://api.box.com/2.0/ai/ask" \
     -H "content-type: application/json" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -d '{
    "mode": "single_item_qa",
    "items": [
        {
            "id": "12345678",
            "type": "file",
            "content": "This is a document about Box AI For documents. It consists of the functionality summary and guidelines on how to work with Box AI. Additionally, it provides a set of best practices for creating questions."
        }
    ],
    "prompt": "List the guidelines on creating questions in Box AI for Documents"
}'
The response to this request is based on the content parameter instead of the file’s content: 
{
    "answer": "The document does not provide specific guidelines on working with questions in Box AI for Documents. It only mentions that it includes a set of best practices for creating questions, but the details of those guidelines are not included in the text provided. If you have more information or another document, I can help further!",
    "created_at": "2024-11-04T02:31:51.125-08:00",
    "completion_reason": "done"
}

​
Ask questions with citations parameter

Setting the citations parameter to true causes the response to include excerpts from source file or files Box AI used to compile the answer. 
curl -i -L POST "https://api.box.com/2.0/ai/ask" \
     -H "content-type: application/json" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -d '{
    "mode": "multiple_item_qa",
    "include_citations": true,
    "items": [
        {
            "id": "12345678",
            "type": "file"
        }
    ],
    "prompt": "List the guidelines on working with responses in Box AI for Documents"
}'
The resulting answer includes the source file and direct content citations. 
{
    "answer": "The guidelines for working with questions in Box AI for Documents are as follows:\n\n1. Box AI pulls information only from the document loaded in preview, and cannot answer questions outside its scope.\n2. Be specific when asking questions; use parameters like numbered lists, brevity, tables, and central themes or key points.\n3. Examples of better phrasing include asking for a numbered list of key points instead of just \"list key points,\" and requesting a succinct outline of important points rather than a general inquiry about the document's purpose.\n4. Stay within the scope of the document and focus on text-based responses only.",
