# List Included Users

> List active members with their plan and extra usage limit

List active human members, change a plan, and set the extra usage limit. 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 invite or deactivate members. Use the [User Management API](https://docs.langdock.com/en/developer/user-management-api/user-management-overview.md) for that.

> [!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/users
```

## 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
* `USER_MANAGEMENT_API` on the same key when you need `email`, `name`, or an email filter

`plan` is `business` or `business_max`. `email` is an exact address and ignores case. `limit` defaults to 50 and cannot exceed 250. Pass `cursor` from `nextCursor`.

To look a member up by email, call `GET /users?email=jane%40example.com` with a key that also has the User Management scope, then update by the returned `id`.

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