Facebook Ad Copy API
Written creative copy from a Meta ad — headline, body, CTA, landing URL.
Returns the ad's written copy — headline, body text, CTA and landing URL. Meta does not expose ad audio, so this is not a speech transcript. Paste a Meta Ad Library ad URL or ad ID. There is no speaker, start, duration, timestamp, or segments array (those belong on instagram/transcript and tiktok/transcript). The path /ad-transcript is kept for compatibility. Always 2 credits.
