# Set a user plan

`PUT /billing/v1/ai-models-included/users/{userId}/plan`

## Request

- Base URL: `https://api.langdock.com`
- URL: `https://api.langdock.com/billing/v1/ai-models-included/users/{userId}/plan`
- Auth: HTTP bearer

Setting the current plan is a no-op. Upgrading resolves the associated pending usage request. May add paid seats; subscription synchronization follows the saved seat change. extraUsagePeriodSpend is null in the response.

## Request body

- IncludedPlanPut
  - `plan` 'business' | 'business_max', required

## Response `200`

Updated resource. Spending is null; GET retrieves spending.
