The TikTok Ad Library is EU-only (EU Digital Services Act ad transparency). Use an EU region such as DE, FR, IE, or NL.
Matching is on the legal entity name, not the brand. Searching nike returns entities like NIKE Retail B.V. and NIKE COM SRL — a brand often spans several legal entities, and some are only discoverable via an ad’s advertiser.adv_biz_ids on Get Ad Detail.
Each request costs 5 credits. Failed requests are not charged.
