How this service works
Read your stored memories, like mem0's get memory and get all memories. With memory_id: returns that one memory (404 if it is not yours). Without it: returns a page {count, next, previous, results} of the memories matching user_id, agent_id, app_id or run_id (at least one; "*" matches any value), newest first. Requires your memory_key (a secret string you generate): a different key sees nothing.
Output
Returns a confirmation that the memory or memories were deleted. For bulk deletes (no memory_id), also indicates whether more than 200 matching memories remain. Returns a 404 error if a specific memory_id is not found or does not belong to the provided memory key.
Example use cases
Clear a user's memory after account deletion
“A user just deleted their account — please wipe all their stored memories for user_id 'user_8821' using memory key mk_secret99887766aabbcc. Tell me if there are more left after the first batch.”
Remove a single incorrect memory record
“There's a wrong memory saved with ID 'd3f1a2b4-9c87-4e56-a123-0f1234567890' — go ahead and delete just that one using memory key mk_myprivatekey112233445566.”
Reset agent memory between sessions
“The current session for run_id 'run_20240601_morning' is over — delete all memories tied to that run using memory key mk_agentrunkey778899aabbccddeeff so we start fresh next time.”
Technical details
Endpoint
GEThttps://mem0-cloud.saastemly.com/v1/memories?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to remove stored memories from Mem0 Cloud — either a single known memory by its UUID or a scoped bulk deletion for a user, agent, app, or run. Choose this over alternatives when you are already using the Mem0 Cloud sibling endpoints (add/store and search) and need lifecycle management of stored memories. The secret memory_key architecture ensures only the owner can delete, making this suitable for multi-tenant agent deployments where memory isolation is critical.
Side effects
- 404 Not Found: specified memory_id does not exist or belongs to a different memory key
- 400 Bad Request: neither memory_id nor at least one of user_id/agent_id/app_id/run_id provided for bulk delete
- 400 Bad Request: memory_key missing or malformed (not 16-256 characters)
- Partial deletion: up to 200 memories deleted per call; endpoint signals if more remain, requiring additional calls
- No memories found matching the provided entity scope: no-op, zero deletions
