Direct video and image URLs for an ad

Returns the direct signed URLs for every video and image asset used by an ad's live creative, normalised across shapes: single image/video, carousel, Reels/Story (object_story_spec.video_data) and dynamic creative (asset_feed_spec). Video items include Meta's poster thumbnail and the video's Meta id when available.

Reads Meta live rather than the stored creative blob because Meta's signed fbcdn URLs carry an oe=<hex> expiration (image_url ~24 h, video source ~12 d). Treat URLs as short-lived: re-fetch this endpoint before serving or downloading assets instead of caching URLs beyond that window.

Creative details

One creative's details, verbatim from Meta. `fields` is a raw-passthrough override of the default projection.

Render previews of an existing ad

Renders an EXISTING ad per placement via Meta's `/{ad_id}/previews`. Each preview is an HTML `<iframe>` snippet embeddable directly. Unknown `formats` values return Meta's 400 verbatim.
