Google Ads Transparency Center Advertiser Search API

Returns the Google Ads Transparency Center advertisers whose name matches a query, every match rather than the search box's first ten. Each advertiser has its AR ID (the one its ads and page use), name, country, verification and ad count as Google's range. Filter to advertisers whose ads ran in one country, with their counts there, and sort by Google's order or most ads first.

One schema on 27 platforms.

The response reference lists every field, its type and when it is null. See the full schema.

Null means unknown
A field Google Ads Transparency Center doesn't show is null, never zero or an empty string, so a real zero always means zero.
What it accepts
An advertiser's name, or a part of it, as typed into the Ads Transparency Center's search box, in any language (nike, lululemon athletica, トヨタ).
Write one parser
Google Ads Transparency Center, TikTok, Instagram and 24 more platforms answer in these fields, so the code that reads one reads them all.

platformstring: Platform ID (tiktok, youtube, …).
idstring: Platform-native account ID (string; YouTube UC…, Reddit t2_…).
usernamestring: Handle without the @; null when the account has none.
display_namestring: Display name, channel title or page name; null when empty or not exposed.
urlstring: Canonical profile URL.
typestring: Coarse account kind, as the platform labels it; unknown when it does not (TikTok labels organizations only). New values may be added; treat unknown values as unknown.
biostring: Profile bio, channel description or page about text; null when empty or not exposed.
avatar_urlstring: Profile picture URL (largest available). Platform CDN URLs can expire within hours.

What teams build with the Google Ads Transparency Center Advertiser Search API.

Find a brand's advertiser IDs across countries
Pick a company's main account by ad count
Check whether Google verified an advertiser
Map the advertisers behind a name

Good to know before you build.

A brand usually has several advertisers, one per legal entity and country (Nike, Inc. in the US, Nike Retail BV in the Netherlands): sort=popular puts the largest first, where Google's own order often doesn't.
sort=popular ranks the matches a walk reaches, Google's most relevant first. For a very broad query (a single letter) that is not every match, so a larger advertiser further down Google's order is not ranked. A brand's name ranks all of its advertisers.
Ad counts are Google's ranges (thousands are bucketed): metrics.post_count is the lower bound, listed in approximate_fields, and platform_specific.google.ads has both bounds. With country, they count only the ads shown there.
Only advertisers are returned. The Google Ads Transparency Center Search Suggestions API also returns the websites the center's search box suggests, and the Google Ads Transparency Center Ads by Website API finds a website's ads by its domain.
A query matches names, not IDs: an advertiser's ID finds nothing, and a link is searched as words, which match no name. Send an ad's or an advertiser's link to the endpoint that takes it. Another Ads Transparency Center page (a domain search) is refused.

Cache hits are free.
Credits from packs and top-ups never expire.
A monthly plan's credits are spent first, and what is left of them ends at each renewal.
Prices exclude tax: sales tax is added at checkout where it applies.
Outside the US, plans and packs are sold to businesses: checkout asks for your VAT, GST or other business tax ID.
