Add lenses to your app. The SDKs are coming soon; until they ship, your app uses the delivery API, which is live today. You need an API key (Workspace → API keys; it is shown once) and a published item's ID (from the Developers page). 1. Resolve a version: GET https://mirage-api.ingevora.com/v1/lenses/:lensId (latest) or /v1/lenses/:lensId/versions/:version (pinned) with the X-Api-Key header; screen effects use /v1/effects/… the same way. 2. Download the manifest from manifestUrl and check that its bytes hash to manifestSha256. 3. Download every asset beside the manifest and check each against the sha256 the manifest records. 4. Render it, following the rendering contract for the product. When a call fails: 401 the key is missing, wrong or revoked; 403 that product is not on for your workspace; 404 not found, not published, or not yours; 429 monthly delivery limit reached.
