`kagi translate`

Translate text through Kagi Translate and return one JSON envelope with the core translation plus the auxiliary text-mode sections. Translate demo

Synopsis

kagi translate [OPTIONS] <TEXT>

Description

kagi translate uses your existing KAGI_SESSION_TOKEN, bootstraps a translate_session at runtime, then calls the live translate.kagi.com endpoints over HTTP. By default the command fetches:

language detection
translated text
alternative translations
text alignments
translation suggestions
word insights

If an auxiliary section fails, the core translation still succeeds and the failure is recorded in warnings. Plain kagi translate "..." means --from auto --to en. The CLI detects the source language first, then translates to English unless you pass --to.

Authentication

Required: KAGI_SESSION_TOKEN The command follows the same Session Link auth story as other subscriber features. Save the full Session Link URL with:

kagi auth set --session-token 'https://kagi.com/search?token=...'

Bootstrap

The CLI uses your existing KAGI_SESSION_TOKEN to fetch https://translate.kagi.com/, reads the returned translate_session cookie from Set-Cookie, then uses normal Rust HTTP requests for the rest of the flow.

Troubleshooting

Bootstrap failure

If translate bootstrap fails before detection or translation starts, the session token is likely invalid for the current account state or Kagi changed the cookie bootstrap behavior.

Invalid session token

Refresh your Session Link and save it again:

kagi auth set --session-token 'https://kagi.com/search?token=...'

Auxiliary section warnings

If warnings is non-empty, the translation succeeded but one or more optional follow-on calls were rejected or unavailable.
