Approve a headless installation
Approves headless enrollment for an API-key or OAuth principal. The installer supplies its P-256 public key, PKCE challenge and requested root ceilings. The returned enrollment_ticket is a one-use credential valid for 120 seconds: redeem through the signed Device transport and never log it. Device lifetime is separate. Execution feature gates can return 503.

}Authorizations
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
Organization id or slug. Resolve it with GET /v3/self.
Body
application/json
Single-use P-256/PKCE headless enrollment. Persistent TTL defaults to 30 days (maximum 90 days); ephemeral defaults to 1 hour (maximum 24 hours). Minimum TTL is 60 seconds. Root fingerprints and permissions are the approval ceiling; unknown fields, including device_kind and bound_run_id, are rejected.
