nullFields Meta Ad Library cannot giveMeta Ad Library gives every field of this call. Where one item lacks a value, that field is null.
Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format
What to expect.
One call returns a page of up to 30 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits.
1 call per second per key, 5 after a purchase; going over is not charged. Rate limits
A failed call costs 0 credits and is never retried on its own. Error codes

Questions.
Short answers.
Everything on Meta Ad LibraryDo 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.
