Research direction

Start by reproducing the warning with the Python 3.14 command from the issue, then inspect cloudflare/_compat.py around the import from pydantic.v1.typing. Check how the package’s Pydantic v2 models use this compatibility module. Done means importing cloudflare on Python 3.14 no longer emits the reported UserWarning while supported behavior remains intact.

Description

Confirm this is a Python library issue and not an underlying Cloudflare API issue.
  • This is an issue with the Python library
Describe the bug

When importing the cloudflare package under Python 3.14, a UserWarning appears from the _compat.py module:

/.../.venv/lib/python3.14/site-packages/cloudflare/_compat.py:48: UserWarning: Core Pydantic V1 functionality isn't compatible with Python 3.14 or greater.
  from pydantic.v1.typing import (

The library uses Pydantic v2 for its models, but still imports from the pydantic.v1 namespace for compatibility. This warning originates from Pydantic itself, which now emits it on Python ≥ 3.14.

To Reproduce
python3.14 -m venv .venv
source .venv/bin/activate
pip install cloudflare
python -c "import cloudflare; print(cloudflare.__version__)"
