Not working with numeric indicators

[bramtayl]

I get

r$> wb_data("9080000")
Error: World Bank API request failed for indicator 9080000 The following message was returned from the server
id: 175
key: Invalid format
value: The indicator was not found. It may have been deleted or archived.

failed request:
https://api.worldbank.org/v2/en/country/all/indicator/9080000?footnote=y&cntrycode=y&per_page=20000&format=json

But the indicator definitely exists:
