Create filters for interesting events on the Ethereum blockchain. Filters include individual address activity, transactions involving a particular token, transfers that fall within a certain value range, and more. You will receive notifications to the URL of your choice each time a pre-specified event occurs.
There are millions of transactions in Ethereum, but only the transactions which match the filter will be sent to the callback URL you have set.
