Poll for Work
beta.environments.work.poll(environment_id, **kwargs) -> BetaSelfHostedWork
GET/v1/environments/{environment_id}/work/poll

Acknowledge Work
beta.environments.work.ack(work_id, **kwargs) -> BetaSelfHostedWork
POST/v1/environments/{environment_id}/work/{work_id}/ack

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.

Record Heartbeat
beta.environments.work.heartbeat(work_id, **kwargs) -> BetaSelfHostedWorkHeartbeatResponse
POST/v1/environments/{environment_id}/work/{work_id}/heartbeat

List Work Items
beta.environments.work.list(environment_id, **kwargs) -> SyncPageCursor[BetaSelfHostedWork]
GET/v1/environments/{environment_id}/work

Get statistics about the work queue for an environment.

Models
class BetaSelfHostedWork: type: "work"; id; acknowledged_at; ... # 10 more

Work resource representing a unit of work in a self-hosted environment.

Work items are queued when sessions are created or when long-dormant sessions receive new messages. The environment worker polls for work to execute in a self-hosted sandbox.

class BetaSelfHostedWorkHeartbeatResponse: type: "work_heartbeat"; last_heartbeat; lease_extended; ... # 2 more

Response after recording a heartbeat for a work item.

type: Literal["work_heartbeat"]

The type of response

defaultwork_heartbeat
last_heartbeat: str

RFC 3339 timestamp of the actual heartbeat from DB

lease_extended: bool

Whether the heartbeat succeeded in extending the lease

state: Literal["queued", "starting", "active", 2 more]

Current state of the work item (active/stopping/stopped)

One of the following:
"queued"
"starting"
"active"
"stopping"
"stopped"
ttl_seconds: int

Effective TTL applied to the lease

class BetaSelfHostedWorkListResponse: data; next_page

Response when listing work items with cursor-based pagination.

class BetaSelfHostedWorkQueueStats: type: "work_queue_stats"; depth; oldest_queued_at; ... # 2 more

Statistics about the work queue for an environment.

Uses Redis Stream consumer group metrics for O(1) queries.

type: Literal["work_queue_stats"]

The type of object

defaultwork_queue_stats
depth: int

Number of work items waiting to be picked up (lag from consumer group)

oldest_queued_at: Optional[str]

RFC 3339 timestamp of oldest item in the work stream (includes both queued and pending items), null if stream empty

pending: int

Number of work items being processed (polled but not acknowledged)

default0
workers_polling: Optional[int]

Number of workers that have polled for work in the last 30 seconds. Requires worker_id to be sent with poll requests.

class BetaSelfHostedWorkStopRequest: force

Request to stop a work item.

force: Optional[bool]

If true, immediately stop work without graceful shutdown

defaultfalse
class BetaSelfHostedWorkUpdateRequest: metadata

Request to update work item metadata.

metadata: Dict[str, Optional[str]]

Metadata patch. Set a key to a string to upsert it, or to null to delete it. Omit the field to preserve existing metadata.

class BetaSessionWorkData: type: "session"; id

Work data for session work items.

This resource type is used when work represents a session that needs to be executed in a self-hosted environment.

type: Literal["session"]

Type of work data

id: str

Session identifier (e.g., 'session_...')
