Once the configuration has been completed and the integration is activated Arctic Hub will poll the data related to the queries hourly. And it will automatically only read new data so you don't see duplicates. You can optionally also configure a max query limit / poll to preserve your query credit quota.
Note: Arctic Security also has a curated list of ready-made Shodan queries that are available under the Shodan by Arctic Security integration.
