Problem extracting data from JSON

Hey there,

 

I've been trying to paginate an API from World Bank, but it does not work. Basically, I list how many pages are to be listed in the final table (which by default loads only 50 rows), but as the custom function is invoked, the following error message pops up:

DataFormat.Error: We found an unexpected character in the JSON input.
Details:
    Value=<
    Position=0

 

Here is the link to the file.

 

Does anyone know what I'm doing wrong and how to make it work?

Simple enough

let
    Source = Xml.Tables(Web.Contents("http://api.worldbank.org/v2/country"))[#"Attribute:pages"]{0},
    Pages = Table.FromList({"1"..Source}, Splitter.SplitByNothing(), {"Page"}),
    #"API Call" = Table.AddColumn(Pages, "API Call", each Xml.Tables(Web.Contents("http://api.worldbank.org/v2/country?page="&[Page])))
in
    #"API Call"


Expertise = List.Accumulate(


        {Days as from Today},


        {Skills and Knowledge},


        (Current, Everyday) => Current & Day.LeanAndPractise(Everyday)


)
