Supported Fields

Message Content

Supported content blocks:

• { "type": "text", "text": "..." }
• { "type": "image", "source": { "type": "url", "url": "..." } }
• { "type": "image", "source": { "type": "base64", "media_type": "image/png", "data": "..." } }
• { "type": "tool_use", "id": "...", "name": "...", "input": { ... } }
• { "type": "tool_result", "tool_use_id": "...", "content": "..." }

Streaming

When stream: true, the route emits Anthropic-style SSE events such as:

• message_start
• content_block_start
• content_block_delta
• content_block_stop
• message_delta
• message_stop
• error

Tool calls stream as Anthropic tool_use content blocks so Claude Code can continue multi-step workflows.
