A workspace is the container everything lives in. Agents, tools, corpora, knowledge bases, phone numbers, and API keys all belong to exactly one. Workspaces are the isolation boundary: an API key reaches its own workspace and nothing else.
Workspaces are managed in the dashboard, under Workspace. There is no API-key endpoint for creating or listing them — those routes authenticate with your dashboard session.

Members and roles

Who pays

The person who created the workspace is billed for everything that happens in it. Not the member who placed the call, not the holder of the API key — the creator. That means a team member’s calls, an API key’s calls, and calls arriving on a workspace phone number all draw from one balance. It is what makes shared usage predictable.
Billing follows workspace creator, which is a fixed record rather than a transferable role. If the person who created a workspace leaves the company, usage still bills against their account — moving it means recreating the workspace under someone else. Worth thinking about before a founder or contractor sets one up on your behalf.

Why separate workspaces

Because the boundary is real, splitting is the cheapest way to get isolation:
  • Environments — staging calls cannot touch production agents, and a leaked staging key exposes nothing live.
  • Customers — if you resell or run agents for clients, one workspace each keeps their agents, documents, and usage genuinely separate.
  • Teams — separate budgets, separate blast radius.
Revoking a key affects one workspace. That is the main practical argument for splitting early: it is much easier than untangling one shared workspace after something goes wrong.

Keys and workspaces

Every API key carries the workspace it was created in, and scopes every request to it. A key cannot see another workspace’s agents — requests for them return 404 rather than 403, so a key cannot even confirm that an ID it lacks access to exists.
Keys created before workspaces existed remain scoped to the user who made them and continue to work unchanged.

Product access

A workspace is entitled to specific products, which controls what appears in the dashboard and which routes it can reach. Most workspaces are voice workspaces.
