Initialize Prefab with an API key, create a context, and evaluate a flag.

import os from prefab import Prefab, Context client = Prefab(api_key=os.environ.get('PREFAB_API_KEY', '')) context = Context(user_key="user-123", attributes={"plan": "premium"}) flag = client.check("my-feature-flag", context) print("Flag enabled:", flag)

Debug
Known issues
breakingThe import path changed from 'import prefab_cloud_python' to 'from prefab import Client/Prefab' in version 0.11.0.
fix
Replace 'import prefab_cloud_python' with 'from prefab import Prefab' and update usage accordingly.
affects: <0.11.0
gotchaContext must be passed to most flag evaluations; omitting it may lead to incorrect results.
fix
Always create a Context with at least a user_key and pass it to client.check().
affects: >=0.12.0
deprecatedThe 'PrefabConfig' object is deprecated in favor of 'Prefab' and 'Client'.
fix
Use 'Prefab' class with api_key parameter directly.
affects: <0.11.0
