Modify/Select sources to answer from

[AravAct]

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 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]

I haven't managed to get this to work.

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