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 YYYY-MM-DD firstShown/lastShown (search omits those). platform=tiktok, library=dsa, media[] objects {url,type,expiresAt} — expiresAt is x-expires / VExpiration / expire= to the second, or null when the URL is unsigned (never midnight-of-fetch). 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).

Response structure

A successful call returns success and a data object with the following fields:

platformPlatform identifier for this response (matches the endpoint's platform).
idStable platform ID for the item.
urlCanonical URL of the item.
textText content.
adFormatFormat of the ad creative.
firstShownCalendar day the ad was first shown (YYYY-MM-DD). TikTok publishes day granularity — not a UTC midnight instant and not MM/DD/YYYY.
lastShownCalendar day the ad was last shown (YYYY-MM-DD). Same day-granularity rule as firstShown.

The /api/v1/cdn/{unix}/ path segment is not an expiry. width/height/durationSeconds are omitted — TikTok DSA has not been observed to publish them.

Frequently asked questions

What does the TikTok Ad Details API do?+

The TikTok Ad Details API lets you fetch full metadata and key stats from a public TikTok Ad Library ad using one GET request to /v1/ad-library/tiktok/ad-details. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the TikTok Ad Details API cost?+

Each successful call costs 2 credits. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.

Do I need a TikTok Ad Library API key or OAuth?+

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

Why was expiresAt already in the past on a live video?+

That was a fabricated midnight. We used to treat /api/v1/cdn/{unix}/ as an expiry and floor it to 00:00:00Z. expiresAt is now parsed from VExpiration, x-expires, or expire= to the second. When none of those params exist — typical for library.tiktok.com — the key is null. A null means "no signed expiry", not "already dead".

What format are firstShown and lastShown?+

Calendar-day YYYY-MM-DD, same as Facebook ad-details. TikTok publishes day granularity. We do not emit MM/DD/YYYY display strings or T00:00:00.000Z instants.

Is the TikTok Ad Details API suitable for production use?+

Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
