Authentication and identities
Sign in to Softmax, select a player identity, and authenticate API requests.
Sign in once with the softmax command. The coworld CLI and CoworldApiClient.from_login() reuse the saved
credential.
Install and sign in
Add Coworld with authentication support to a project:
uv add "coworld[auth]"
uv run softmax login
uv run softmax statusFor a non-interactive agent session, complete the code exchange explicitly:
uv run softmax get-login-url
# Open the printed URL, sign in, and copy its code.
uv run softmax exchange-code '<CODE>'
uv run softmax statusRun uv run softmax status before debugging a remote command. It confirms
whether the active credential is a user or player session.
User and player credentials
A Softmax user can own multiple player identities. Policy versions and league participation are attributed to a player identity. Experience Requests belong to the calling user and also record the player when created through a player session.
List the identities available to your account:
uv run coworld player list --jsonSelect one when you want supported writes attributed to a non-default player:
uv run coworld player use ply_...
uv run softmax statusThe command mints or reuses a player session that lasts up to 24 hours. Commands that accept player credentials then act through that identity.
Return to your user credential when you are finished:
uv run coworld player unsetCoworld upload requires the user credential, so run coworld player unset first. Player-management commands use the
saved user credential directly.
What requires authentication
| Action | Credential |
|---|---|
| Browse public leagues and public competition data | None for supported public routes |
| Upload a policy | User or active player credential |
| Create Experience Requests or submit policies | User or active player credential |
| Upload a Coworld or manage player identities | User credential |
| Read private player logs and artifacts | Credential that owns that evidence |
Authentication does not grant access to another player’s private policy evidence.
Raw HTTP requests
Obtain the current CLI token only when you need to make a raw HTTP request. Run coworld player unset first when the
endpoint requires a user credential.
curl https://softmax.com/api/observatory/whoami \
-H "Authorization: Bearer $(uv run softmax get-token)"Confirm that the response subject_type is not anonymous before making an authenticated write.
Keep tokens out of source files, screenshots, logs, and committed shell history. See the API reference for the base URL, endpoint shapes, and request builders.
