Referrer-PolicyJSON; {"enum":["strict-origin-when-cross-origin","no-referrer"]}The default referrer policy is strict-origin-when-cross-origin. Provider-login responses use no-referrer to protect login parameters.
VarystringResponses vary by Accept-Language; browser-rendered responses can also vary by the preference cookie.
X-Content-Type-OptionsJSON; {"const":"nosniff"}The browser must use the declared content type.
X-Frame-OptionsJSON; {"const":"DENY"}The response must not be embedded in a frame.
X-Request-IDstringServer-generated request identifier. Include this when reporting an error; inbound values are not trusted.

Retries and asynchronous work

This operation reads or validates without applying a resource mutation. Respect rate limits and credential lifetime.

Request examples

Replace demo IDs, timestamps and placeholders with your own values. For a retry, keep the same IDs, time and content. These examples do not run requests on this page.

Keep login links, codes, cookies and keys private. Do not print them in logs or share them in support requests.

  • HTTP API, OAuth and MCP

    Find the user API endpoints, their permissions, fields, examples and response formats.

  • DELETE End every other active browser session

    End all other active browser sessions, including sessions outside the loaded pages. The current session and account are checked again inside the transaction. The current session, machine credentials, device keys and MCP tokens are retained. Repeating the request succeeds with revoked equal to zero. No email code is required.

  • DELETE Revoke one of your sessions

    Revoke one of your sessions.

  • POST Request a code for one sensitive action

    Request a six-digit confirmation code for a sensitive account or workspace change. It lasts five minutes and allows five incorrect attempts. Use the same signed-in browser, action, target and parameters when confirming. A replacement requested after 60 seconds invalidates the previous code for that action. For your own account use link_identity, unlink_identity, add_passkey, remove_passkey or delete_self; workspace membership actions require owner permission. Do not use sign-in codes to confirm changes.
