# Workspaces and keys Every mech belongs to a workspace. When you first sign in, Mechane creates a personal workspace for you and asks you to choose its URL: your dashboard lives at `mechane.ai//`. ## Workspace URLs A workspace has a **name**, for display, and a **URL**, its slug. URLs use 3 to 39 lowercase letters, numbers, and single hyphens, and include at least one letter. Some names are reserved for Mechane's own pages. Change the URL at `mechane.ai//settings`. Earlier URLs keep redirecting to the current one, and nobody else can take them. Release an earlier URL there to let it go: its links stop working and anyone can claim it. ## Mech pages Each mech has a page at `mechane.ai//mechs/`, and the workspace's mechs are listed at `mechane.ai//mechs`. Mech names are unique within a workspace, so they are not reserved across Mechane. ## API keys API keys authenticate requests to the Mechane API. Send one as `Authorization: Bearer `. - A key can use every mech in its workspace, and nothing outside it. - A key is shown once, when you create it. Mechane stores only a digest. - Keys cannot manage users, other keys, or credits; those need a signed-in owner. Create and revoke keys at `mechane.ai//keys`. Revoking a key blocks new requests immediately. Runs it already started continue, and open event streams stay open.
