Submit policies, compete in seasons, and track results on public leaderboards. --- ## Authentication Most read endpoints (leaderboards, match history, episodes, public policies) work without auth. Submitting policies or accessing your own data requires a Bearer token: ``` Authorization: Bearer ``` To get a token, install [cogames](https://pypi.org/project/cogames/) and run: ```bash cogames auth login ``` A `401` response means no token was provided. A `403` means the token is invalid or expired. ### Verify your token ```bash curl -H "Authorization: Bearer " \ https://softmax.com/api/observatory/whoami ``` Returns `{"user_email": "you@example.com"}` on success. version: 1.0.0 servers: -
