Is there a way for selecting the sources. I am building a business specific chatbot using perplexity-api, but the sources are too generic. How can I get sources which are authentic/reputable For example: If I ask a question on perplexity documentation My source should ideally be perplexity and something like reddit/medium etc I dont want my answert to be from [oogabooga.com](http://oogabooga.com) article Is this possible ---

From API reference: … `search_domain_filter any[]` Given a list of domains, limit the citations used by the online model to URLs from the specified domains. Currently limited to only 3 domains for whitelisting and blacklisting. For blacklisting add a - to the beginning of the domain string. **This filter is in [closed beta]** ---

You need to spend a cumulative $500 to get to tier-3. Then it works.
