You should probably return a JSON object in that case.

Mainly that it shows how one could programmatically access these documents. You would just need to get the "id" and "token". The URL is put in the first URLFetch is really made up of pieces and one can take advantage of that.

comment Getting rid of sub-exponential terms in an asymptotic expansion for a modified Bessel function

great answer, but could be also combined into one plot with: DensityPlot[a[x] - b[x, y], {x, -5, 5}, {y, -5, 5}, MeshFunctions -> (b[#1, #2] &), Mesh -> 5]
