# List Included Groups

> List groups with the extra usage limit that applies to each member

Read groups and set an extra usage limit for each member of a group. The limit is not a shared pool. Amounts are euros.

The calls use the workspace API key's `BILLING_API` scope. Writes run as the key's service account owner. This API does not add or remove group members.

> [!NOTE]
>
> Call these routes when `GET /billing/v1/mode` returns `ai-models-included`. Dedicated deployments always return `bring-your-own-keys`, including when Langdock manages the model keys. The other mode returns `409` with `code` `BILLING_MODE_MISMATCH`.

## Base URL

```
https://api.langdock.com/billing/v1/ai-models-included/groups
```

## Prerequisites

* **API key** with the `BILLING_API` scope
* The key owner is a service account that has not been deleted and has an active Admin membership

`limit` defaults to 50 and cannot exceed 250. Pass `cursor` from `nextCursor`.

The list response is `{ "groups": [ ... ] }` and includes `nextCursor` until the last page. Each group is the object described on [Get Included Group](https://docs.langdock.com/en/developer/billing-api/get-included-group.md).
