We don't use the `config/api.yml` file since commit c984e666f, and the
`.delete("\n").delete(" ")` in the code examples isn't necessary (we
should have probably added it in commit 56e42f209).
We're also changing the responses so there are no references to any
specific city.
We were getting many errors when trying to run them, from uninitialized
constant `HTTP` to undefined method `headers`.
We might move these examples to the documentation repository in the
future, but we need to look for possible side-effects first.
