Tour location array not an array?

When using the API to create a tour ( the documentation outputs that the result should be an array of locations in right sorting (
It appears however that it is outputting a series of nested objects as json array’s typically start and end with block quotes ( [’’] ) and not the curly brackets ( {’’} ).

Our software is unable to parse this as a list for this reason. Did we do something wrong or perhaps call the wrong API method? Is there a setting in the call to alter the results?
