Ad Intelligence API FAQs

What is an ad intelligence API?
An ad intelligence API lets you search and retrieve structured data about which companies are actively running ads across major paid channels. Filter by ad channel and recency, then get back the channels each company is advertising on, when their last ad was seen, and direct links to source ad libraries.
Which ad platforms are supported?
CompanyEnrich tracks company-level ad activity on Meta (Facebook and Instagram), Google, and select professional ad networks. Each result returns the platforms a company is running ads on and direct ad-library links for verification.
Can I find companies that started running ads recently?
Yes. Use last_ad_seen_after to return companies whose ads were observed after a given date. A common pattern is to set this to 30 days ago to surface companies actively spending right now.
Can I filter by platform and combine with industry or size?
Yes. Combine ad_platforms with firmographic filters like industries, country, employee count, revenue range, and technologies to narrow a list of active advertisers to your exact ICP.
What fields are returned per company?
Each match returns is_running_ads, platforms, last_ad_seen, and ad_libraries with direct links to each platform's public ad library. Firmographics like industry, employee count, revenue range, location, and technologies are returned alongside.
Does the API return ad creatives and copy?
The API returns company-level ad activity, platform coverage, last-seen dates, and direct ad-library links. Use those links to review creative and copy in the source platform libraries.
Can I check whether one company is running ads?
Yes. A dedicated single-company endpoint returns the same ad signals for a known account, useful for appending paid-acquisition signals to CRM records you already have.
