Each POST to /v1/serp/google-ads returns up to 40 ads from the Google Ads Transparency Center, with the depth param controlling how many you page through. Each ad keeps its position in the result set.
Every result identifies the advertiser behind the ad and its verification status, so you can confirm exactly which company is running a creative for a keyword or topic.
Each item returns the ad's creative text and its format, letting you collect real competitor copy and ad types for benchmarking and inspiration.
Set the location and language fields to see ads as they run in a specific country and locale, since advertisers tailor creatives and targeting per market.
The type field on each result lets you distinguish ad formats returned by the Transparency Center so you can filter to the creative types you care about.

console.log(data);Google Ads Transparency API — see what competitors are advertising
The YepAPI Google Ads Transparency API searches the Google Ads Transparency Center and returns running ads as structured JSON. Send a keyword or advertiser and get back which ads are live, who is running them, their creative text, and format.
It uses the same key as the rest of YepAPI's SERP, scraping, and AI endpoints, so competitive ad research plugs into your wider intelligence pipeline at $0.01 per query.
What is a Google Ads Transparency API?
A Google Ads Transparency API lets you programmatically search Google's Ads Transparency Center and get structured results on the ads companies are actively running. For a keyword or advertiser it returns the advertiser name and verification status, the ad creative text, the ad format, and the type of each result, ordered by position. That means you can answer which competitors are advertising on a topic, what copy and formats they run, and confirm the verified entity behind each ad — all from a single request instead of manually browsing the Transparency Center one advertiser at a time.
Build your own competitive ad research tool
With Transparency Center data as JSON you can build a competitor ad-monitoring tool, a creative swipe-file builder, or a market-intelligence dashboard. Query your competitors and target keywords on a schedule, store advertiser, creative text, and format for each ad, and flag when new creatives appear. Because each result carries verification status you can filter to confirmed advertisers, and combine it with the YepAPI organic SERP endpoint to compare who buys ads versus who ranks organically for the same terms.
Google Ads Transparency API pricing — $0.01 per query
Each call to /v1/serp/google-ads is a flat $0.01 for up to 40 ads, with no subscriptions or minimums. SerpApi charges $0.05 per query and competitive-intelligence suites cost far more per lookup. YepAPI prices every SERP endpoint at the same $0.01, so continuously tracking competitor ad activity across many keywords stays cheap and predictable.
Benchmark PPC creative and market activity
The Transparency Center reveals what your competitors actually run, not what they claim. Use the endpoint to pull live ad copy and formats for your category, benchmark your own creatives against them, and spot new entrants bidding on your keywords. Re-run queries with different location and language values to see how advertisers localize messaging, which helps you tailor your own campaigns market by market.
