->This limit is important because the default user VirusTotal apikey only allows to process a certain nunmber of queries per minute. As a consequence it is recommended to have a larger number of requests or a private apikey.
+>Compared to the [standard VirusTotal expansion module](https://github.com/MISP/misp-modules/blob/master/misp_modules/modules/expansion/virustotal.py), this module is made for advanced parsing of VirusTotal report, with a recursive analysis of the elements found after the first request.
