how to get youtube `search instead` feature in youtube api version 3?

Question

In youtube interface if we search for a term with spelling mistake, Interface provides an option to "search instead" for a similar term. for example poovin maarile search gives you results for poovin marile

but while using youtube api version 3, poovin maarile gives zero results and poovin marile gives 230+ results. But there is no way in the api to get this very closely related term.

I am aware of spelling suggestions feature in version 2 but since version 2 is deprecated I am not interested in using it. Is there something similar for youtube data api version 3?

Answer 1

I don't think there's an official API for this at the moment.

You probably shouldn't rely on this being available in the future, but I think the only alternative at the moment is querying the same URL that YouTube and other pages use.

From another question: Youtube API search auto-complete

A page detailing the query parameters: Google Autocomplete API
