已超出Google趋势API npm配额

Question

我正在使用Google Trends API获取历史趋势数据。我正在从CSV文件中读取关键字并触发谷歌趋势查询。 这是代码

var googleTrends = require('google-trends-api');
var fs = require('fs')
fs.readFile('merged.csv', 'utf8', function (err,data) {
        if (err) {
                return console.log(err);
        }
        data = data.toString().split("\n");
        recur(0, data);
});

function recur(index, data){
        if (index < data.length){
                var keyword = data[index].split(",")[0];
                console.log(keyword);
                googleTrends.trendData(keyword)
                .then(function(results){
                        console.log(results);
                        index = index+1;
                        recur(index, data);
                })
                .catch(function(err){
                        console.error('We have an error!', err);
                });
        }
}

我在
