Agents and agent pools API reference

An Agent Pool represents a group of Agents, often related to one another by sharing a common network segment or purpose. A workspace may be configured to use one of the organization's agent pools to run remote operations with isolated, private, or on-premises infrastructure.

List Agent Pools

GET /organizations/:organization_name/agent-pools

ParameterDescription
:organization_nameThe name of the organization.

This endpoint allows you to list agent pools, their agents, and their tokens for an organization.

StatusResponseReason
200JSON API document (type: "agent-pools")Success
404JSON API error objectOrganization not found

Query Parameters

This endpoint supports pagination with standard URL query parameters. Remember to percent-encode [ as %5B and ] as %5D if your tooling doesn't automatically encode URLs.

ParameterDescription
qOptional. A search query string. Agent pools are searchable by name.
sortOptional. Allows sorting the returned agents pools. Valid values are "name" and "created-at". Prepending a hyphen to the sort parameter will reverse the order (e.g. "-name").
page[number]Optional. If omitted, the endpoint will return the first page.
page[size]Optional. If omitted, the endpoint will return 20 agent pools per page.
filter[allowed_workspaces][name]Optional. Filters agent pools to those associated with the given workspace. The workspace must have permission to use the agent pool. Refer to Scoping Agent Pools to Specific Workspaces.

Response fields

Responses for this endpoint can contain an attributes object with the following fields:

Field nameTypeDescription
data.attributes.agent-countnumberThe number of agents in Idle, Busy or Unknown states. Agents that are Exited or Errored are excluded.
data.attributes.meta.status-counts.totalnumberThe total number of resources the filter was applied to.
data.attributes.meta.status-counts.matchingnumberThe total number of resources returned, which match the filter you applied.
