SIGMORA_API_KEY.
Why there is no workspace in the path
The key is the tenant. Putting a workspace id in the URL would mean a key holder could name a workspace, and every route would then have to prove that key may act for it — an impersonation surface with no upside. The workspace is resolved from the credential instead, and cannot be overridden.Roles
Checking your own usage never requires a key that can spend.
Where a key is valid
A workspace key opens/v1 and nothing else. The engine behind it serves an
internal surface as well — the unpriced routes our own frontends call — and a
sk_live_… key is refused there with 403 forbidden, naming /v1 as the place
the credential belongs. There is no path that runs a priced capability without
pricing it.
Rotation and containment
Keys are stored hashed, never recoverably — losing one means minting a replacement, not retrieving the original. Revocation takes effect immediately.A key cannot mint another key. Key management is a session-only surface, so
a leaked key cannot be used to establish persistence.
