All Implemented Interfaces:

dev.case.api.core.Params
```
public final class ChatSendMessageParams
 implements Params
                    
```
Sends a message and returns the complete response as a single JSON body. Blocks until the agent turn completes.
When to use this endpoint: Best for server-to-server integrations, background processing, or any context where you want the full response in one call without managing an SSE stream.
Alternatives:
- POST /chat/:id/respond — streaming SSE with normalized events (recommended for custom chat UIs)
