Python
# To use the Python SDK, install the package:
# pip install mem0ai

from mem0 import MemoryClient
client = MemoryClient(api_key="your_api_key", org_id="your_org_id", project_id="your_project_id")

# Delete all memories for a specific user
client.delete_all(user_id="<user_id>")

# Delete all memories for every user in the project (wildcard)
client.delete_all(user_id="*")

# Full project wipe — all four filters must be explicitly set to "*"
client.delete_all(user_id="*", agent_id="*", app_id="*", run_id="*")

# NOTE: Calling delete_all() with no filters raises a validation error.
# At least one filter is required to prevent accidental data loss.
