# REST API

If you prefer to work directly with the REST API instead of a [Cloudflare Worker](https://developers.cloudflare.com/workers-ai/features/batch-api/workers-binding/), below are the steps on how to do it:

## 1\. Sending a Batch Request

Make a POST request using the following pattern. You can pass `external_reference` as a unique ID per-request that will be returned in the response.

Sending a batch request

```

curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/ai/run/@cf/baai/bge-m3?queueRequest=true" \

 --header "Authorization: Bearer $API_TOKEN" \

 --header 'Content-Type: application/json' \

 --json '{

    "requests": [

        {

            "query": "This is a story about Cloudflare",

            "contexts": [

                {

                    "text": "This is a story about an orange cloud"

                },

                {

                    "text": "This is a story about a llama"

                },

                {

                    "text": "This is a story about a hugging emoji"

                }

            ],

            "external_reference": "reference-1"

        }

    ]

  }'


```

```

{

  "result": {

    "status": "queued",

    "request_id": "768f15b7-4fd6-4498-906e-ad94ffc7f8d2",

    "model": "@cf/baai/bge-m3"

  },

  "success": true,

  "errors": [],

  "messages": []

}


```

## 2\. Retrieving the Batch Response

After receiving a `request_id` from your initial POST, you can poll for or retrieve the results with another POST request:

Retrieving a response

```

curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/ai/run/@cf/baai/bge-m3?queueRequest=true" \

 --header "Authorization: Bearer $API_TOKEN" \

 --header 'Content-Type: application/json' \

 --json '{

    "request_id": "<uuid>"

  }'


```

```

{

  "result": {

    "responses": [

      {

        "id": 0,

        "result": {

          "response": [

            { "id": 0, "score": 0.73974609375 },

            { "id": 1, "score": 0.642578125 },

            { "id": 2, "score": 0.6220703125 }

          ]

        },

        "success": true,

        "external_reference": "reference-1"

      }

    ],

    "usage": { "prompt_tokens": 12, "completion_tokens": 0, "total_tokens": 12 }

  },

  "success": true,

  "errors": [],

  "messages": []

}


```
