What is the recommended way to query Accounts based on AccountHistory?

//query
String query = 'Select Name, Id, OwnerId From Account Where ID IN: (Select AccountId From AccountHistory)';

//batch class
SendAccounts sender = new SendAccounts(query)
Database.executeBatch(sender);
//batch class definition
global class SendAccounts implements Database.Batchable<sObject>, Database.AllowCallouts{
   global final String Query;
   global SendAccounts (String qry){
      Query=qry; 
   }
   global Database.QueryLocator start(Database.BatchableContext BC){
      return Database.getQueryLocator(query);
   }
   global void execute(Database.BatchableContext BC, List<sObject> scope){
     //perform logic
     //make 1 http callout
    }
   global void finish(Database.BatchableContext BC){
   }
}
