LibreTranslate supports per-user limit quotas, e.g. you can issue API keys to users so that they can enjoy higher requests limits per minute (if you also set `--req-limit`). By default all users are rate-limited based on `--req-limit`, but passing an optional `api_key` parameter to the REST endpoints allows a user to enjoy higher request limits.
|
||||
|
||||
To use API keys simply start LibreTranslate with the `--api-keys` option. If you modified the API keys database path with the option `--api-keys-db-path`, you must specify the path with the same argument flag when using the `ltmanage keys` command.
