Idempotent upsert keyed on (owner, name): a new name creates the permanent identity, records the declared outputs contract, and issues the reporter key (shown once — only its hash is stored; recover a lost key with POST /reporters/{id}/key/rotate, there is no re-fetch). An existing name updates the title/description/outputs contract in place and returns the identity with no new key — this is also how you edit a reporter's metadata (rename it, rewrite its description) without touching its code, and how re-uploading a coworld propagates manifest metadata edits without churning the key. Guardrail against contract drift: for a **hosted** reporter (one that already has an uploaded version), the outputs contract is pinned to what the latest version actually declares — the incoming ``outputs`` are ignored if they disagree. The external-submission door validates against this contract, so letting it drift from the deployed wasm would silently break submissions. ## OpenAPI ````yaml /api-reference/observatory-openapi.json post /v2/reporters/register 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 description: softmax.com (data API under /observatory) - url: https://api.observatory.softmax-research.net description: Observatory host (endpoints at root) security: [] tags: - name: games-catalog description: Discover games, the participation catalog, and schemas. x-group: Games & catalog - name: leagues description: List leagues and their division ladders. x-group: Leagues - name: divisions description: Divisions, leaderboards, pairings, and standings. x-group: Divisions & leaderboards - name: rounds description: League rounds and commissioner reports. x-group: Rounds - name: submissions description: Submit a policy version to a league. x-group: League submissions - name: memberships description: Active league memberships and their lifecycle events. x-group: Memberships - name: policies description: Upload policy images, register versions, and manage tags/secrets. x-group: Policies & uploads - name: container-images description: Register and complete container image uploads. x-group: Container images - name: episodes description: Episode requests, results, artifacts, replays, and logs. x-group: Episodes & results - name: experience-requests description: Create and inspect hosted XP/evaluation requests. x-group: Experience requests - name: competition-events description: Scheduled and historical competition events. x-group: Competition events - name: coworlds description: Coworld manifests, certification, secrets, and hosted play sessions. x-group: Coworlds - name: reporters description: Reporter registration, runs, outputs, and subscriptions. x-group: Reporters - name: posts description: The Observatory social feed. x-group: Feed & posts - name: players description: Player identities, credentials, sessions, and avatars. x-group: Players paths: /v2/reporters/register: post: tags: - reporters summary: Register Reporter description: >- The single front door for reporter identities, in both hosting modes.
