`created_at` is not included in request body

>>> import memobase
m>>> memobase.__version__
'0.0.24'
>>> from memobase import ChatBlob
>>> from datetime import datetime
>>> timestamp = datetime(2025, 9, 1)
>>> b = ChatBlob(messages=[
...     {"role": "user", "content": "Hi, I'm here again"},
...     {"role": "assistant", "content": "Hi, Gus! How can I help you?"}
... ], created_at=timestamp)
>>> b.to_request()
{'blob_type': <BlobType.chat: 'chat'>, 'fields': None, 'blob_data': {'messages': [{'role': 'user', 'content': "Hi, I'm here again", 'alias': None, 'created_at': None}, {'role': 'assistant', 'content': 'Hi, Gus! How can I help you?', 'alias': None, 'created_at': None}]}}

The generated request body sets created_at to None. This field is excluded during model_dump() according to this line of code. As the result, the created_at (and updated_at) fields defined in the API are not accessible through the Python SDK directly.

Hi, created_at and updated_at are contained if you request a Blob data from Memobase, they shows the timestamp of the Blob in DB, they're not supposed to add at requests. If you want to denote the time of messages, you can try set the time in each message, like this:

memobase/assets/quickstart.py

Line 18 in f0ebb97

"created_at": "2025-01-14",
