{/* Generated by scripts/generate-api-reference.mjs from data/api-reference.json. Do not edit. */}

Classify text or images into categories. Zero-shot and few-shot classification. Zero-shot uses embedding similarity, few-shot uses a trained classifier.

- **Tool id:** `jina-classify`
- **Provider:** [Jina Reader API](/providers/jina)
- **Job:** [Sort texts into your own labels](/reference/jobs/text-classify) (`text.classify`)
- **Price:** $0.0002 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `classifier_id` | string | no | ID of the trained classifier to use. |
| `input` | unknown | yes | Text to classify: a string, `TextDoc`, or list of up to 512 items. |
| `labels` | unknown | yes | Candidate labels: a list of up to 512 labels, or a dict of up to 8 groups with max 64 labels each. |
| `model` | string | yes | The code embedding model to use. Example: "jina-embeddings-v3" |

## Output

The run's `result` holds the provider's answer. Signed in, `looot inspect jina-classify` prints its fields.

## Run it

Every call needs your API token in `LOOOT_TOKEN`; [Sign in](/get-started/sign-in#use-the-token-in-scripts-and-agents) shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With `wait: 30` the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll `GET /v1/runs/<runId>`.

Example input with placeholder values:

<CodeGroup>

```bash curl
curl -X POST "https://api.looot.ai/v1/runs" \
  -H "Authorization: Bearer $LOOOT_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"endpointId":"jina-classify","input":{"model":"jina-embeddings-v3","input":["I love this product"],"labels":["positive","negative"]},"wait":30}'
```

```js JavaScript
const response = await fetch("https://api.looot.ai/v1/runs", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LOOOT_TOKEN}`,
    "Content-Type": "application/json",
    "Idempotency-Key": crypto.randomUUID(),
  },
  body: JSON.stringify({
    endpointId: "jina-classify",
    input: {
      model: "jina-embeddings-v3",
      input: ["I love this product"],
      labels: ["positive", "negative"],
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);
```

```python Python
import os
import uuid

import requests

response = requests.post(
    "https://api.looot.ai/v1/runs",
    headers={
        "Authorization": f"Bearer {os.environ['LOOOT_TOKEN']}",
        "Idempotency-Key": str(uuid.uuid4()),
    },
    json={
        "endpointId": "jina-classify",
        "input": {
            "model": "jina-embeddings-v3",
            "input": ["I love this product"],
            "labels": ["positive", "negative"],
        },
        "wait": 30,
    },
    timeout=90,
)
run = response.json()
print(run["status"], run.get("result"))
```

To let looot pick among every provider of this job instead, send `job:text.classify` as `endpointId`; see [the job page](/reference/jobs/text-classify).
