# Meta ad detail API

The Meta ad detail API returns one ad of the Meta Ad Library by its library ID or link: advertiser, text, headline, images and videos, landing page, first and last day shown, the platforms it is delivered on, and whether it is still running. One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Call it over HTTP or from your AI client over MCP. Last tested 2026-10-17.

## FAQ

**Do I need a Meta Ad Library account or Meta Ad Library's own API access?**

No. You only need a SocialToAI key. The call returns content and account information publicly visible on Meta Ad Library; you never sign in to Meta Ad Library or apply for anything there.

**What does “Preview” mean here?**

Preview: this interface is not marked stable yet, so its parameters and fields may still change. It is charged like any other call, and a failed call is not charged.
