Example prompt: Can you search the LinkedIn Ad Library for ads from Salesforce — keyword 'CRM' — in the US between January 1 2025 and March 31 2025?

## When to prefer this

Use this endpoint when you need to search across multiple LinkedIn ads by company name, keyword, or company ID — especially for competitive research, ad monitoring, or market intelligence. Prefer this over the single-ad lookup endpoint when you need discovery or bulk retrieval rather than fetching a specific known ad.

## Known failure modes

- No ads found matching the query — empty results list returned
- Invalid date format causes validation error
- Invalid country code returns no results or error
- Missing required search parameter (company, keyword, or companyId) results in error
- Pagination cursor from a different query causes unexpected results
- Rate limiting or quota exceeded returns an error response

## How this service works

Search LinkedIn Ad Library ads by company, keyword, or company id.

## Output

A paginated list of LinkedIn Ad Library ad records matching the search criteria, including ad creatives and advertiser metadata, plus an opaque cursor for fetching the next page of results.
