claude-agent-sdk swallows API error messages, returns unhelpful "Unknown error"

[beatboxchad]

My API key is from anthropic.com whereas my claude account is from claude.com. My code kept giving me this vague error:

 File "/usr/local/lib/python3.13/asyncio/runners.py", line 195, in run
    return runner.run(main)
           ~~~~~~~~~~^^^^^^
  File "/usr/local/lib/python3.13/asyncio/runners.py", line 118, in run
    return self._loop.run_until_complete(task)
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^
  File "/usr/local/lib/python3.13/asyncio/base_events.py", line 725, in run_until_complete
    return future.result()

    async for message in query(prompt=prompt, options=options):
    ...<3 lines>...
                    response_text += block.text
  File "/usr/local/lib/python3.13/site-packages/claude_agent_sdk/query.py", line 123, in query
    async for message in client.process_query(
    ...<2 lines>...
        yield message
  File "/usr/local/lib/python3.13/site-packages/claude_agent_sdk/_internal/client.py", line 120, in process_query
    async for data in query.receive_messages():
        yield parse_message(data)
  File "/usr/local/lib/python3.13/site-packages/claude_agent_sdk/_internal/query.py", line 598, in receive_messages
    raise Exception(message.get("error", "Unknown error"))
Exception: Command failed with exit code 1 (exit code: 1)
Error output: Check stderr output for details

When I tested the API directly with cURL, I got a much more helpful message:

{
  "type": "error",
  "error": {
    "type": "invalid_request_error",
    "message": "Your credit balance is too low to access the Anthropic API. Please go to Plans & Billing to upgrade or purchase credits."
  },
  "request_id": "req_011CWPC2UU2DQ7ND9gxnUSCt"
}

You should capture those API error messages and save us some more time :)

Thanks for this beautiful work, thrive on!
