Issue a scoped, short-lived agent token for one account
POST /api/v1/agent-tokens · operationId issueAgentToken
For developers: your server sends this request with a server key; it is not a button in the dashboard.
409 agent_tokens_disabled while agent tokens are off for the Site (Settings); 409 tool_not_approved or tool_not_read_only for a tool that is not reviewed and enabled, or that changes data (writes stay in the page). Retrying issues another token: keep the first answer.
Authentication
Send Authorization: Bearer YOUR_SERVER_KEY (siteServerKey: Site server key in Authorization: Bearer <key> (the scheme is case-insensitive and required; a bare key is 401). Shown once on creation or rotation. Publishable keys cannot authenticate). Keep the server key in server-only configuration; never send it to a browser.
