Google Ads Transparency Center Advertiser Search API Documentation

This API allows you to search for advertisers in the Google Ads Transparency Center using a given keyword. It returns a list of advertisers, each with an ID, region, and number of ads, as well as a separate list of domains that are being advertised.

It is accessible via the /api/v1/search?engine=google_ads_transparency_center_advertiser_search endpoint.

You can later use either the advertiser ID or a domain with the Google Ads Transparency Center API to retrieve the actual ads associated with them.
