Lists the A/B tests and lift studies on a Meta ad account, with their timing and test groups.
Lists the ad account's A/B tests and lift studies (Meta's /act_X/ad_studies), rows
returned verbatim. The default projection covers id, name, type, timing and cells with
split percentages; fields is a raw-passthrough override.

Query Parameters
Zernio SocialAccount id (posting or ads variant) used to resolve the Meta token.
Meta ad account id (act_).
Comma-separated Graph field override. Supports nested {} projections and Graph field modifiers, so a nested edge can be paged explicitly: without a .limit() modifier the expansion runs at the Meta default page size and the tail is dropped silently.
Rows per page
1 <= value <= 10025Cursor from paging.after of the previous page.

Returns the TikTok Business Centers (BCs) the connected `tiktokads` account can read. Each BC reports its advertiser count so callers can build agency-style pickers without re-walking `/v1/ads/accounts` per BC. TikTok-only. Solo advertisers (non-agency tokens) return an empty array.
List Instagram ad identities
Lists the Instagram accounts a Meta ad connection can run ads as, so you can pick the identity for a new ad. Discovers identities through connected_instagram_accounts, Page linkage and Page-backed identities, with a best-effort business fallback. Business permission errors do not fail discovery. The resolved object uses the same profile-scoped resolver as ad creation; null means no identity was resolved. Format-specific observed-actor fallbacks at creative creation are not predicted.
