Use this API to manage environments (the org-scoped primitive workspaces are created from — including variables, files, skills, MCPs, warm hooks, start hooks, and warm pools), create and manage replicas, send messages, manage chats, stream events, read connected repositories and repository sets, and configure automations. servers: - url: https://api.tryreplicas.com description: Production API security: - apiKey: [] tags: - name: Environments description: >- Manage environments — the primitive that workspaces are created from. Variables, files, skills, MCPs, warm-hooks, and warm-pools are all scoped to an environment. Every organization has a singleton Global environment whose values apply to every workspace. Personal environments are scoped to the authenticated user and can be standalone or source-backed by a team environment. - name: Repository description: >- Read repositories and repository sets connected to your organization. Repositories are the underlying GitHub-connection layer; bind them to an environment to use them in workspaces. - name: Replica description: >- Manage replicas (workspaces) for AI agents. `/v1/replica` endpoints accept API keys and workspace engine-secret authentication; user-session JWTs are not accepted. - name: Terminal description: Manage interactive terminal sessions in active workspaces - name: Preview description: Manage public preview URLs for workspace ports - name: Profile description: Read and update the authenticated user's profile - name: Credentials description: >- Manage coding-agent credentials for an organization or the authenticated user - name: Google Search Console description: >- Read Search Console properties, performance, sitemaps, and URL inspection results through a connected Google account - name: Slack description: Connect Slack identities and route threads to Replicas workspaces - name: Linear description: Connect Linear identities to Replicas accounts - name: Automation description: >- Create and manage automations that trigger replicas on a schedule or in response to events - name: Downloads description: Download Replicas applications - name: Media description: >- Read workspace media and obtain short-lived download or inline preview URLs - name: Analytics description: >- Read aggregated activity and usage metrics for your organization: compute minutes, workspaces created by source, and pull request throughput over a time range. - name: Presence description: >- Read and report ephemeral member presence: who is online, where they are (environment or workspace), and whether they are typing.
