Every ad your competitors run — as clean JSON
One REST API for the Meta, TikTok, LinkedIn and Google ad libraries. Search commercial ads by keyword or advertiser and get creative URLs, run dates and advertiser metadata — no app review, no OAuth, no scrapers to maintain.
What the official APIs don't give you
The official Meta Ad Library API returns political and social-issue ads only in most countries, gates access behind app review, and withholds creative files. Here is the gap, side by side.
Four ad libraries, one schema
Every platform returns the same uniform JSON shape — withheld fields are null, never missing. Switch platforms without rewriting your parser.
Meta (Facebook & Instagram)
Search the Meta Ad Library by keyword or brand, list a company's ads, pull ad details and even ad transcripts. Commercial ads included — not just political.
TikTok
Query TikTok's Commercial Content Library (EU DSA) by keyword, pull the Creative Center top-ads leaderboard, and resolve calendar-day run dates per ad.
Search the LinkedIn Ad Library by advertiser or keyword and hydrate ad details — copy, CTA, format, advertiser and, when LinkedIn publishes them, run dates and impressions.
Read the Google Ads Transparency Center: list an advertiser's ads, search advertisers, and pull ad details across Search, Display, YouTube and Shopping.
What every ad returns
- Ad copy, headline & CTA
- Creative image & video URLs
- Advertiser name, id, page & logo
- First/last shown dates (when published)
- Impressions & targeting (when published)
- Landing / destination URL
- Platform & ad format
- Uniform JSON — withheld fields are null, never missing
Built for ad intelligence
If you're building a competitor ad-tracking dashboard, a swipe-file tool, or feeding creatives to an AI agent, you need bulk, reliable access across platforms — not a scraper you babysit or an official API that hides commercial ads. That's exactly this.
Frequently asked questions
What is an Ad Library API?+
An Ad Library API returns the ads that brands are running — from public ad transparency libraries like the Meta Ad Library, TikTok Commercial Content Library, LinkedIn Ad Library and Google Ads Transparency Center — as structured JSON instead of a web page. Captapi puts all four behind one REST endpoint set so you can search ads, list a competitor's creatives, and pull ad details programmatically.
How is this different from Meta's official Ad Library API?+
Meta's official Ad Library API only returns political and social-issue ads in most countries, requires identity verification and app review, and does not hand you the creative files. Captapi returns commercial ads too, needs no app review, includes creative image/video URLs, and covers TikTok, LinkedIn and Google alongside Meta with the same JSON shape.
Do I need app review or a Facebook login?+
No. You get an API key and call the endpoints directly — no Meta app review, no OAuth, no logging into any platform. That is the single most common reason developers move off the official API.
Which platforms are covered?+
Meta (Facebook & Instagram), TikTok (Commercial Content Library / Creative Center), LinkedIn Ad Library, and Google Ads Transparency Center — 13 endpoints in total, all behind one consistent REST interface.
Can I get the ad creative images and videos?+
Yes. Where the library exposes them, responses include creative image and video URLs so you can build swipe files, spy dashboards, or feed an AI agent — not just the ad text.
How much does it cost?+
Ad-library calls are billed per call in credits, and failed calls are never charged. You start with 100 free credits, no credit card. See the pricing page for current plans and per-endpoint credit costs.
Is scraping public ad libraries allowed?+
Ad libraries are public transparency tools that platforms are required to provide (reinforced by the EU's Digital Services Act). Reading them for competitor research is exactly what they exist for. Captapi runs and maintains that collection for you.
