If you are a free user of VirusTotal, VT Graph quota is consumed from the API quota of your VirusTotal account. Your saved graphs are public and available to VirusTotal community.
Basically API requests are consumed by:
- The initial resource search.
- Every parent node type.
- Each time you click on a file to retrieve the additional information shown on the left side.
If you are a VirusTotal Enterprise customer, VT Graph quota is not consumed from your VirusTotal API quota. VirusTotal Intelligence quota is consumed for each nodes you start your investigation with, each time a node is added manually and when you search using "Expand using new intelligence search". Your saved graphs will be private if you have enough Private Graph quota or warned otherwise before we save the graph public.
