{"answer":"Recommended action: Use api-key header for keys (AzureOpenAI(api_key=...)), or azure_ad_token_provider with scope https://cognitiveservices.azure.com/.default (cloud-specific for sovereign clouds); refresh tokens via a provider rather than a static token.\n\nOption: Match auth header/scope to credential type [evidence: documented_workaround]\nApplies when: Azure OpenAI clients\nSteps:\n1. Keys: send api-key header (use AzureOpenAI client, not a generic OpenAI client with Bearer)\n2. Entra: get_bearer_token_provider(cred, \"https://cognitiveservices.azure.com/.default\")\n3.
