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

Creates or updates a reusable list of AI Ark people or company ids, to exclude from People Search, Company Search and Export People with Email. Send values and type (people_id or company_id); send an existing id to update it, with mode APPEND (default) or REPLACE. Lists hold up to 10,000 items and expire after 24 hours; up to 50 lists per day.

- **Tool id:** `ai-ark-lists`
- **Provider:** [AI Ark](/providers/ai-ark)
- **Job:** [Get lists](/reference/jobs/lists-get) (`lists.get`)
- **Price:** $0 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | no | Existing list id to update. Omit to create a new list. |
| `mode` | string | no | <code>APPEND</code> (default) merges the values into the list; <code>REPLACE</code> overwrites it. |
| `type` | string | no | <code>people_id</code> or <code>company_id</code>. Required when creating. |
| `values` | array | yes | The IDs to store (person or company ids, matching <code>type</code>). Max <strong>10,000</strong> per list. |

## Output

The run's `result` holds the provider's answer. Signed in, `looot inspect ai-ark-lists` 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":"ai-ark-lists","input":{"values":[]},"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: "ai-ark-lists",
    input: {
      values: [],
    },
    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": "ai-ark-lists",
        "input": {
            "values": [],
        },
        "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:lists.get` as `endpointId`; see [the job page](/reference/jobs/lists-get).
