  "account": "Claude API workspace verification helps catch misrouted requests before they are attributed to the wrong workspace. When a multi-workspace credential sends a request, Anthropic now returns the actual workspace ID in the response. The verification process compares the routing configuration with an independent authorization mapping and then compares that with the workspace ID in the response. This helps ensure that the application is using the correct workspace for the request, which is important for cost dashboards, resource management, and avoiding unexpected failures. The verification should run after a successful HTTP response but before the response body is processed by the application. The check should compare the intent (routing target), the authorized workspace (from a separate mapping), and the resolved response workspace ID. If any of these values don't match, an exception is thrown. This verification only proves that the response resolved to the expected workspace; it doesn't grant access to the workspace or replace provider authentication. The check needs to be deterministic and independent of the component choosing the routing header, and it should be run as part of CI tests.",
  "summary": "Claude API workspace verification is a small check that closes an awkward observability gap. A multi-workspace credential can send a request toward one workspace, while a stale deployment setting, copied ID, or routing mistake points somewhere else. If I record only the configured workspace, every later cost and resource lookup begins with an assumption. Anthropic now returns…",
