Agent Pools and Agents API

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.

Note: Terraform Cloud Free Edition includes one self-hosted agent. Refer to Terraform Cloud pricing for details.

List Agent Pools

GET /organizations/:organization_name/agent-pools

Parameter	Description
`:organization_name`	The name of the organization.

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

Status	Response	Reason
200	JSON API document (`type: "agent-pools"`)	Success
404	JSON API error object	Organization 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.

Parameter	Description
`q`	Optional. A search query string. Agent pools are searchable by name.
`sort`	Optional. 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.
