Hello, studying to make a small application with PAI I found a mistake.
Below is the link that I used, see what I look for a city in São Paulo (SP), the API brings me the results of the neighboring towns, then, it is showing a city of the Federal District (DF) that is not part of the content.
I have helped the community.

Sincerely Bruno Kaue.
