# Validate the stored canvas graph

`GET /v1/collections/{id}/canvases/{canvasId}/validate`

## Request

- Base URL: `https://api.masko.ai`
- URL: `https://api.masko.ai/v1/collections/{id}/canvases/{canvasId}/validate`
- Auth: HTTP bearer

> **Deprecated.**

Checks graph structure and assigned media references without generating media or changing the graph. Draft edges without videos report missing-video; this is expected before animation generation. GET requires read access. A structurally invalid graph still returns 200 with data.valid=false.

## Path parameters

- `id` string, uuid, required
- `canvasId` string, uuid, required

## Response `200`

Graph validation result.

    - `summary` object, required
      - `errors` number, required
      - `warnings` number, required
