Ad API: Every Type Explained (Management, Public, Third-Party)

An ad API is a programmatic interface to advertising data — either to manage your own ad accounts, or to read public ad data from platforms like Meta, TikTok and Google. Marketers, agencies and analytics teams all use ad APIs; they do very different things depending on which side of the wall you sit on. This guide explains every kind of ad API, when to use which, and the trade-offs nobody documents.

The three types of ad API

Management ad APIs

A management ad API lets you create campaigns, upload creatives, change budgets and pull performance metrics for ad accounts you own. Every major ad platform ships one:

• Meta Marketing API — the ad API behind Facebook Ads Manager. Authenticates with OAuth, scopes per account, rate-limited per app.
• Google Ads API — gRPC + REST. Heaviest ad API to learn but the most powerful for reporting.
• TikTok Marketing API — newer ad API, lighter feature surface than Meta's.
• LinkedIn Marketing API — niche but essential for B2B teams running an ad API integration.

Public ad APIs

A public ad API exposes ads visible in a public ad library. The only first-party public ad API at scale is Meta's ads_archive, which is restricted to issue, election and political ads. Google has a similar political ad transparency API; TikTok has a smaller one.

For commercial ads, there is no first-party public ad API. This is exactly why a third market exists.

Third-party ad APIs (for competitive intelligence)

A third-party ad API scrapes public ad libraries on your behalf and serves the data through a clean schema. AdScrape, BigSpy and SocialPeta all run an ad API behind their dashboards. A typical third-party ad API request:

curl -X POST https://api.adscrape.in/v1/search \
  -H "Authorization: Bearer $AD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"brand":"Nike","country":"US","active":true,"limit":50}'

Which ad API do you need?

• Running your own ads? Management ad API (Meta Marketing API + Google Ads API).
• Researching political ad spend? Public ad API (Meta Ad API + Google's).
• Tracking competitors' commercial ads? Third-party ad API (AdScrape or similar).
• Building an analytics SaaS? Probably two of the above stitched together.

Ad API authentication: OAuth, app tokens and API keys

Management ad APIs all use OAuth — the user grants your app permission to act on their ad account. Public ad APIs use long-lived app tokens with platform-issued permissions (e.g. ads_archive on Meta). Third-party ad APIs use simple bearer keys you mint in the provider's dashboard. Mixing the three in one product means three different auth flows in your codebase.

Ad API rate limits to plan around

The AdScrape ad API in one minute

AdScrape's ad API is a REST endpoint over the Facebook Ad Library. Authenticate with a bearer token, POST a search payload, get JSON back. Free tier is 100 ad API calls per month; paid plans scale to 100k+. We also expose a brand comparison ad API endpoint that returns two competitors side-by-side, a feature no first-party ad API offers.

Ad API FAQ

What is an ad API?

An ad API is any programmatic interface to advertising data — your own ad accounts, public ad libraries, or scraped competitor data.

Is the Meta Ad API the same as the Meta Marketing API?

No. The Meta Ad API (ads_archive) returns public political ads. The Meta Marketing API manages your own ad accounts. Different scopes, different permissions.

Is there a free ad API?

Yes. The official Meta Ad API is free for political ads. AdScrape's ad API offers a free tier for commercial ads.

Can one ad API cover Meta + Google + TikTok?

No single first-party ad API covers all three. Tools like Supermetrics aggregate multiple ad APIs behind one façade.

Do I need an ad API if I have a dashboard?

Only if you want to embed ad data elsewhere — a BI tool, a warehouse, an internal app or an LLM workflow. For one-off research, a dashboard is enough.
