### Errors

- `400` (Error): The request is malformed, or failed input validation. `message` names the field and the rule it broke; `data.issues` carries them individually.
- `401` (Error): No bearer token, or a token that failed verification.
- `402` (Error): The workspace has no credits left, or the caller is over a spending limit.
- `403` (Error): Authenticated, but the caller's role in this workspace does not carry the permission this operation needs.
- `409` (Error): The request is well-formed, but the resource's current state forbids it — a taken name, a last admin, a limit already reached.
- `429` (Error): The caller has spent its rate-limit window. `Retry-After` says when to come back.
- `500` (Error): The request failed on our side. Safe to retry an idempotent operation with backoff.
