Mapping values from a collection inside an array with dynamic name inside a collection

I need to access the city value and map it in the set variable module that follows this HTTP GET request module but the challenge is that the 98601 (postcode) is dynamic, always different on each output.

I tried the following two
{{1.data.results[0][0].city}}
{{get(map(1.data.results; item => get(item; 0).city); 0)}}

but they don’t get recognized as functions.
