Avatar: type: object description: A face preset that a persona can use as its visual representation. properties: id: type: string format: uuid description: Unique identifier for the avatar. displayName: type: string description: Human-readable name shown in the Lab and share links. variantName: type: string description: >- Name of the specific variant (e.g. lighting or pose) within the avatar family. imageUrl: type: string format: uri description: >- Still image of the avatar, framed exactly like `videoUrl`, `idleVideoUrl` and a landscape session (the default). Use it as the thumbnail, poster or loading image wherever a preview video or the live stream replaces it, and give the image and the video the same box, `object-fit` and `object-position` so the avatar doesn't move when they swap. For Cara 4 avatars this is the 1152x768 landscape crop (the same image as `landscapeImageUrl`). Cara 4 avatars used to return their square source image here; that image is now `sourceImageUrl`.

For Cara 4 avatars it is square (1152x1152) and shows more of the scene than the 1152x768 crop that preview videos and sessions use, so the avatar appears to zoom in when a video or call replaces it. Don't use it as a thumbnail, poster or loading image next to `videoUrl` or a session; use `imageUrl`, `landscapeImageUrl` or `portraitImageUrl`.

May be a time-limited link; see `imageUrlsExpireAt`. portraitImageUrl: type: - string - 'null' format: uri description: >- Still image cropped exactly as the engine frames portrait (768x1152) output. Use it as the poster for a session started with portrait `videoWidth`/`videoHeight`. Preview videos are landscape, so don't swap this image for `videoUrl`. `null` when the avatar cannot render portrait output or its images are not available through the API.

They stay valid for at least an hour, and repeated requests within the same hour return the same links, so browsers can cache them. Treat them as credentials for those images, since anyone holding a link can load the image until it expires. `null` when the image URLs don't expire. videoUrl: type: - string - 'null' format: uri description: >- Signed URL for a verified muted MP4 preview of the avatar.
