# REST API

If you prefer to work directly with the REST API instead of a [Cloudflare Worker](https://edgetunnel-b2h.pages.dev/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**

```bash
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"
        }
    ]
  }'
```

```json
{
  "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**

```bash
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>"
  }'
```

```json
{
  "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": []
}
```
