## When to prefer this

Use this endpoint when you need to discover or research advertisers in Google's public Ad Library by name or keyword. It is ideal for competitive intelligence, brand safety monitoring, ad transparency research, or identifying political advertisers. Prefer this over a generic web search when you need structured advertiser data from Google's ad transparency system specifically.

## Known failure modes

- Empty results if query matches no known advertisers in Google's Ad Library
- Rate limiting or HTTP 429 if too many requests are made in quick succession
- Malformed or missing query parameter may return an error or empty response
- Google Ad Library may not surface all advertisers if they have limited ad activity
- Upstream Google Ad Library changes may cause unexpected response structure changes
