Where can I find out the usage of a word by API like on Google Trends?

Question

Node.js

On node.
Found the module https://www.npmjs.com/package/google-trends-api#in...
Returns an array with the following objects:

{ time: '1133395200',
    formattedTime: 'Dec 2005',
    formattedAxisTime: 'Dec 1, 2005',
    value: [ 35 ],
    hasData: [ true ],
    formattedValue: [ '35' ] }

And what should I do with this value? What does it mean? I wanted the number of how often this word was used in the search string, but this figure is not this number. Is it a percentage of something?
