The Foundry endpoint authenticates API-key requests with the x-api-key header. Previously this worked by accident: the base client emitted X-Api-Key from auth_headers. When auth_headers was emptied to stop a stray ANTHROPIC_API_KEY environment variable from leaking to the Foundry endpoint, API-key requests were left with only the api-key header, which the endpoint rejects with a 401. Attach x-api-key (alongside api-key, kept for backwards compatibility) in _prepare_options. This branch only runs when no Azure AD token provider is configured, so the key is always the explicitly provided Foundry key, never an environment ANTHROPIC_API_KEY — the leak fix still holds. Fixes #1661
