# Delete documents or memories

`DELETE /context`

Delete one or more knowledge sources or memories by ID.

## Request body

- SourcesV2SourceDeleteRequest
  - `collection` string — Collection scope. Defaults to the default collection when omitted. Formerly `sub_tenant_id`; the `sub_tenant_id` alias is still accepted (deprecated).
  - `database` string — Database/Collection are the canonical v2 names; TenantID/SubTenantID are their deprecated aliases, reconciled by the TenantAliases middleware before binding so TenantID is always populated.
  - `ids` string[] — IDs of the sources or memories to delete.
  - `sub_tenant_id` string — deprecated: use collection
  - `tenant_id` string — deprecated: use database
  - `type` 'knowledge' | 'memory' — Bucket to delete from: `knowledge` (default) or `memory`.

## Response `200`

OK

- HandlerEnvelopeSourcesMemoryDeleteResponse
  - `data` SourcesMemoryDeleteResponse
    - `deleted_count` integer — Total number of items successfully deleted.
    - `message` string — Human-readable result message.
    - `results` SourcesSourceDeleteResultItem[] — Per-item results.
      - `deleted` boolean — Whether this specific item was deleted.
      - `error` string — Error message for this item, empty string on success.
      - `id` string — Unique identifier for this resource.
    - `success` boolean — Whether the request succeeded.
    - `user_memory_deleted` integer — Number of memory items deleted.
  - `error` HandlerApiError
    - `code` string — Machine-readable error code (e.g. `DATABASE_NOT_FOUND`).
    - `message` string — Human-readable description of the error.
  - `meta` HandlerResponseMeta
    - `api_version` string — APIVersion echoes the version of the API that served the request (PRO-1209), sourced from reqmeta.APIVersion — the same value carried by OpenAPI info.version and /health — so a client always knows which API version produced a response. Always present (no omitempty).
    - `collection` string — Collection scope. Defaults to the default collection when omitted. Formerly `sub_tenant_id`; the `sub_tenant_id` alias is still accepted (deprecated).
    - `database` string — Owning database. Formerly `tenant_id`; the `tenant_id` alias is still accepted (deprecated).
    - `deprecation` HandlerDeprecationNotice[] — Deprecation lists any migration nudges that apply to this request — the caller used a legacy /tenants route, a legacy tenant_id/sub_tenant_id field, or the deprecated sub_tenant_ids selector. It is a non-breaking signal (the status code is unchanged); omitempty keeps it absent for fully-migrated requests. A list so independent deprecations coexist without clobbering.
      - `deprecated` boolean — Whether this response concerns a deprecated field or route.
      - `deprecated_field` string — The deprecated field name.
      - `deprecated_since` string — API version when the field was deprecated.
      - `message` string — Migration guidance message.
      - `preferred_field` string — The canonical replacement for the deprecated field.
    - `latency_ms` number — Server-side processing time in milliseconds.
    - `request_id` string — Unique identifier for this request, useful for support and tracing.
    - `source_type` string — Type of the parent source (e.g. `file`, `slack`, `notion`).
    - `sub_tenant_id` string
    - `tenant_id` string
  - `success` boolean — Whether the request succeeded.
