# Get concurrency

> How many of your workspace's calls are in progress right now, against its concurrent-call limit.

Counted exactly as the limit is enforced: a call holds a slot while it is `queued`, `ringing` or `in-progress`, and a call with no update for an hour holds none.

```bash theme={null}
curl "https://api.verbeo.ai/v2/call/concurrency" \
  -H "Authorization: Bearer YOUR_API_KEY"
```

```json theme={null}
{ "success": true, "data": { "active_calls": 3, "concurrency_limit": 10 } }
```

<ResponseField name="concurrency_limit" type="number">`0` when the workspace has no limit set.</ResponseField>

Use it to pace a batch before you get `429 TOO_MANY_REQUESTS` from [Create phone call](/api-reference/calls/create).
