## List Work Items

`$client->beta->environments->work->list(string environmentID, ?int limit, ?string page, ?list<AnthropicBeta> betas): PageCursor<SelfHostedWork>`

**get** `/v1/environments/{environment_id}/work`

Note: these endpoints are called automatically by the pre-built environment worker provided in the SDKs and CLI, for orchestrating sessions with self-hosted sandbox environments. They are included here as a reference; you do not need to invoke them directly.

List work items in an environment.

  Maximum number of work items to return
