Streaming Response Types

This endpoint uses Server-Sent Events (SSE) for streaming responses, which is why the OpenAPI specification only shows an empty 200 response. The actual streaming response returns the following message types (all exported by @anthropic-ai/claude-code except ErrorMessage):
  • SDKAssistantMessage: Claude’s responses with type 'assistant'
  • SDKUserMessage: User prompts with type 'user'
  • SDKResultMessage: Final results with type 'result' and subtypes:
    • 'success'
    • 'error_max_turns'
    • 'error_during_execution'
  • SDKSystemMessage: System messages with type 'system' and subtype 'init'
  • ErrorMessage: Custom error type with:
    • type: 'error'
    • message
    • timestamp
