How this service works
Facebook Ad Library Search: search the public Meta Ad Library by keyword for ads on Facebook and Instagram. Per ad the page name, ad text, active status, start and end dates, publisher platforms, call to action, landing link and media links in the shared social schema; next_cursor gives the next page. Competitor ad research. Bad input is free; not found or no match is not charged.
Output
A JSON object containing a list of ad items, each with: ad ID, Facebook Ad Library URL, ad text, title, page name, author followers, active status, start/end dates, publisher platforms (FACEBOOK/INSTAGRAM), call-to-action text, landing URL, media image URLs, and language. Also includes the search query echo, a next_cursor for pagination, a request ID, and a disclaimer about data provenance. The 'complete' flag indicates whether all results fit in one page.
Example use cases
Competitor ad creative research
“Pull all the Facebook and Instagram ads currently running for the keyword 'meal kit delivery' — I want to see the ad copy, call-to-action buttons, and the landing page URLs each brand is using.”
Brand ad activity monitoring
“Check the Meta Ad Library for any ads mentioning 'Nike Air Max' — are there active ads right now, when did they start, and what platforms are they running on?”
Niche ad copy inspiration
“Search Facebook ads for 'email marketing software' and give me a list of the ad headlines and CTA text being used so I can see what messaging is working in that space.”
Technical details
Endpoint
GEThttps://social.duoleads.com/v1/facebook/ads?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search the Meta Ad Library by keyword across Facebook and Instagram ads — specifically for competitive ad research, monitoring what creatives competitors are running, finding landing page URLs from ads, or gathering ad copy inspiration. Prefer this over scraping Facebook directly since it handles pagination, returns structured data in a shared social schema, and only charges for successful matches.
Side effects
- No ads found for the keyword returns an empty items array (not charged)
- Invalid or malformed query string returns a bad-input error (not charged)
- Expired or invalid cursor returns a pagination error
- Rate limiting or upstream Meta API unavailability may cause transient failures
- Very broad keywords may return many pages requiring multiple cursor-based calls
