Search the Swiss Ephemeris fixed star catalogue by name, designation or brightness.
1357 rows covering 532 distinct stars — the remainder are alias names, folded into the star they belong to. That matters here: Aldebaran is also Rohini and Sirius is also Lubdhaka, so the Vedic names are searchable, and a naive listing would return Sirius three times.
This is the index you need before asking for anything else, because star names are not guessable. It takes no date and returns no positions — a position needs a date, so use /positions/ for that.
