Query tools by name

The List Tools API now supports querying by tool name.

1 send_message_tool_id = client.agents.tools.list(tool_name="secret_message")[0].id

Authorization header now supports password

For self-deployed instances of Letta that are password-protected, the Authorization header now supports parsing passwords in addition to API keys. X-BARE-PASSWORD will still be supported as legacy, but will be deprecated in a future release.

Before:

1 curl --request POST \
2   --url https://MYSERVER.up.railway.app/v1/agents/ \
3   --header 'X-BARE-PASSWORD: password banana' \
4   --header 'Content-Type: application/json' \
5   --data '{
6     ...
7   }'

After:

1 curl --request POST \
2   --url https://MYSERVER.up.railway.app/v1/agents/ \
3   --header 'AUTHORIZATION: Bearer banana' \
4   --header 'Content-Type: application/json' \
5   --data '{
6     ...
7   }'

Password can now be passed via the token field when initializing the Letta client:

1 client = LettaClient(
2     base_url="https://MYSERVER.up.railway.app",
3     token="banana",
4 )
