## FAQ

### How do I search Facebook for advertising companies?

Send a GET request to /v1/facebook/adlibrary/search/companies with your query keyword. SocialCrawl returns a list of advertising Facebook pages that match, along with active ad counts and basic page details.

### What data does the company search return?

Each result includes the Facebook page name, page ID, category, follower count, active ad count, and verification status. Use this to discover every advertiser in a niche before pulling their full ad catalog.

### How much does advertiser search cost?

Each request costs 5 credits on the advanced tier. New accounts get 100 free credits with no credit card required. Pair this with /v1/facebook/adlibrary/company/ads to fetch every ad from each discovered advertiser.

### Can I find niche competitors without knowing their names?

Yes, that's the main use case. Search for a product category or keyword (like 'ai saas' or 'dtc skincare') and get back every Facebook page actively advertising in that space — even small competitors you hadn't heard of.

### Is this the same data as facebook.com/ads/library?

Yes. SocialCrawl reads the same public Ad Library data you see on facebook.com/ads/library but returns it as structured JSON. Your pipeline gets clean records instead of scraping HTML that breaks when Meta updates their UI.
