Get an ad's videos and images
Resolve a LinkedIn ad's creative into downloadable asset URLs — videos, images and thumbnails, across the main creative and every attachment. LinkedIn's own CDN URLs are signed and expire, so each asset also carries a stable download URL served through this API. Optionally probe each asset to confirm it is still available, or return small assets base64-encoded inline.
