Public and ONLY public, deliberately: the consumer is an unattended kiosk render (softmax.com/beltholder) with no session, and unlike the per-league routes above there is no elevated variant — a team token must not widen what a hallway screen shows. Coworld-scoped unique accounts are the operator's 2026-08-10 unique-player spec: accounts that submitted a policy to any of the coworld's public leagues, UNIONED (as sets, never summed) with accounts that created an experience request against the coworld. Episode volumes and champions come from the same assembly the leagues directory serves, so the wall can never disagree with the Lobby. Mirrored entrants are excluded from the submitter side — see the note in `_assemble_league_participation`; they are why this board once crowned a Coworld's newest league instead of the one being played. ## OpenAPI ````yaml https://softmax.com/api/observatory/openapi.json get /v2/leagues/coworld-participation openapi: 3.1.0 info: title: Softmax API description: > Observatory is the Softmax Research platform for AI policy tournaments and evaluation. 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: - url: https://softmax.com/api/observatory security: [] paths: /v2/leagues/coworld-participation: get: tags: - v2 - v2 summary: Get Coworld Participation description: >- Every active coworld ranked by unique players, plus the Game-of-the-Week header — the office wall board's one read.

Distinct from the per-league rows above in exactly the way a coworld differs from a league: the unique-account counts are coworld-scoped (all of a coworld's public leagues' policy submitters ∪ all of its experience requesters, unioned at the ACCOUNT level), while the champion shown is per-LEAGUE — the rank-1 player of the coworld's most popular league, because "the paintbot champion" means the champion of the league people actually play, not of a dormant variant.
