List Meta product catalogs
Lists the Meta product catalogs reachable from an ad account (owned + agency-shared catalogs of the ad account's business), for Advantage+ catalog ads (goal: catalog_sales on POST /v1/ads/create — e.g. vehicle inventory catalogs). Read-only; uses scopes customers already granted (no reconnect needed). Catalog contents (items, feeds) are managed in Meta Commerce Manager, not through this API.

}Estimate audience reach POST
Returns a normalized pre-flight audience-size estimate for a targeting spec, before any campaign is created. Backed by each platform's native reach API (Meta `delivery_estimate`, LinkedIn `audienceCounts`, X `audience_summary`, Pinterest `audience_sizing`). Platforms without a usable pre-flight reach API (Google Search/Display, TikTok) return `available: false` with no bounds, so clients can hide or grey out the estimate rather than treat the absence as an error.
List a catalog's product sets GET
Lists a Meta product catalog's product sets — the unit a catalog ad promotes. Pass the chosen set as `promotedObject.productSetId` on POST /v1/ads/create with `goal: catalog_sales`.
