## <ApiType type="Class" path="core/google/call_response_chunk" symbolName="GoogleCallResponseChunk" /> GoogleCallResponseChunk
A convenience wrapper around the Google API streamed response chunks.
When calling the Google API using a function decorated with `google_call` and
`stream` set to `True`, the stream will contain `GoogleCallResponseChunk` instances
Example:
```python
from mirascope.core import prompt_template
from mirascope.core.google import google_call
@google_call("google-1.5-flash", stream=True)
def recommend_book(genre: str) -> str:
return f"Recommend a {genre} book"
stream = recommend_book("fantasy") # response is an `GoogleStream`
for chunk, _ in stream:
print(chunk.content, end="", flush=True)
```
