Functions available

lookup

lookup uses destructured parameters to accept arguments marked by the keys which barcodelookup accepts: i.e. barcode, mpn, asin, key, etc.

lookup({ barcode: barcode, mpn: mpn, asin: asin, productName: productName, category: category, 
            search: search, page: page, geo: geo, formatted: formatted, key: key })

lookup returns an object as a promise. The object will contain a status code and either a data packet of products or an error message.

{ statusCode: 200, data: { products: [ [Object] ] } }
...
{ statusCode: 403, data: 'Forbidden' }
...
{ statusCode: 404, data: 'Not Found' }

{ statusCode: 429, data: 'Too Many Requests' }
