Account and Space
Each request uses the account and Space attached to the key. The server checks current account status, membership and access to the requested resource. A request cannot choose another billing identity by adding headers or body fields. Projects and assets use the same ownership rules as the Web app, including its public and user libraries. Webhook subscriptions are account-wide; see Webhook availability. Revoking a key stops subsequent authenticated calls. It does not cancel tasks that were already accepted or refund completed work.API keys and OAuth
Do not send an
Authorization header to the JSON API. Do not send both credential types to MCP. For delegated assistant access, use the MCP OAuth flow.
