Devices

List your Devices

Lists Mac/headless Devices one page at a time: first Devices per page (200 unless given), and when has_next_page is true, end_cursor passed as after reads the next page, so no Device is left out. A Device with its roots is about 3 KB; ask for a smaller first where the size of one response matters. The default owned scope lists the caller’s devices; scope=workspace lists all devices in the workspace for owners and admins. Expired and revoked entries are included, after the Devices that are still connected and unexpired; each group is newest first. Managed infrastructure is excluded. An after this list did not return is refused with 400 invalid_cursor.

Authorizations

Authorization

string

header

required

Your Reason API key from Settings › API keys. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, knowledge:read, memory:read, memory:write, skills:read, skills:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, network:read, network:write, automations:read, automations:write, agent_auth:read. network:read and network:write are opt-in, excluded from default keys. network:read reads the saved workspace network policy; network:write replaces custom allowed hosts and requires a current organization owner/admin. Legacy project PATCH requests containing network_allowed_hosts also require network:write plus their existing run scope and project management permission; saved project hosts do not affect current session egress. Only owners/admins can mint or manage keys with network:write; keys cannot grant themselves more authority. See /docs/network-policies for replacement semantics and runtime applicability. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:read reads sessions, including the assistant, reasoning and tool activity in their events. sessions:debug is privileged: only for organization owners/admins, it expands session events to the full diagnostic projection (diagnostic event kinds, status text and raw event metadata).

Path Parameters

orgId

string

required

Organization id or slug. Resolve it with GET /v3/self.

Query Parameters

scope

enum<string>

default:owned

Whose Devices to list. workspace reads every member's Devices and needs the owner or admin role (403 otherwise); omit it for the caller's own.

Available options:

owned,

workspace

first

integer

default:200

Page size. Each Device with its roots adds about 3 KB to the response, so ask for fewer when one response must stay small; omit it for the largest page.

Required range: 1 <= x <= 200

after

string

Copy end_cursor from the previous listDevices response with the same inventory scope; omit for the first page.

Response

One page of Devices.

devices

object[]

required

Devices on this page: connected, unexpired ones first, then expired and revoked ones, each group newest first.

Show child attributes

end_cursor

string | null

required

Pass as after for the next page; null on the last page.

has_next_page

boolean

required

Whether more Devices follow this page.
