TL;DR

One TikTok Commercial Content Library ad by ID — calendar-day dates, always 2 credits. The TikTok Ad Details API (TikTok Ad Library) is a single authenticated GET request to /v1/ad-library/tiktok/ad-details that responds with clean JSON and costs 2 credits. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the TikTok Ad Details API?

Paste a TikTok Ad Library URL or ad ID and get that creative as clean JSON with the same uniform key set as /tiktok/search (null when withheld) plus calendar-day ISO firstShown/lastShown (search omits those). platform=tiktok, library=dsa, media[] objects, impressions from Unique users seen when disclosed, spend only when shipped. advertiser is always {id,name,url,logo,location} — name is a human label, never a bare numeric id. Always 2 credits on success — native and Apify fallback share one price (no 2-vs-5 surprise). Response includes fetchPath: "native" | "fallback" so you can see which path ran. Default country GB (EU-led library).

What you get

ID lookup with search-parity fields (including impressions)
Uniform null keys + advertiser{id,name,url,logo,location}
Calendar-day ISO firstShown / lastShown
Always 2 credits; fetchPath native|fallback
