Despite the wolframalpha.com giving correct results, any API query of the same exact text
import wolframalpha
client = wolframalpha.Client(abc-123')
res = client.query("cost of living index Austin, TX")
res_string = next(res.results).text
print(res_string)
which prints the (data not available) even though on wolframalpha.com it works fine. Why's that? How fix?
