# Verify Knowledge Base resource

`POST /knowledge-base/resources/{id}/verify`

Mark a Knowledge Base resource (FILE or URL) as verified. Stamps
`lastVerifiedAt` to the current time and resets `expiresAt` forward
by the domain's configured review cadence; the resource's content
(title, description, file or url, tags, owner) is left unchanged.
Caller does not need to know the resource type — the persisted
`resourceType` is used. Returns 404 when the id is unknown in the
domain or — for FILE rows — when the underlying uploaded document
has been deleted.

## Path parameters

- `id` string, required

## Request body

- VerifyKnowledgeBaseResourceInput
  - `expirationDate` string — The expiration date in ISO 8601 format. If omitted, falls back to the configured review cadence.

## Response `200`

Ok

- union — Discriminated union over `type` of all resource kinds in the Trust Knowledge Base (currently FILE and URL).
