# Forget a fact

`DELETE /v1/memory/{memoryId}`

## Request

- Base URL: `https://api.zavu.dev`
- URL: `https://api.zavu.dev/v1/memory/{memoryId}`
- Auth: HTTP bearer

Delete one fact. Idempotent: deleting a fact that is not there, or no longer there, still answers `204`. Deletes are never refused for quota reasons.

## Path parameters

- `memoryId` string, required

## Query parameters

- `scope` string: Scope as a query-string value: `contact:<contactId>`, `conversation:<conversationId>`, the literal `project`, or omitted for project scope. Only the SHAPE of the id is validated, never its existence — the partition already carries your project, so an id that matches nothing simply addresses an empty scope rather than returning 404.

## Response `204`

Fact deleted.

## Other responses

- `400`: Malformed memory id or `scope`.
- `401`: Unauthorized.
