Hi Debprakash,

Please follow below code:-
  
global class CalloutsFromBatchExample implements Database.Batchable<SObject>,Database.AllowsCallouts,Database.stateful{

    public Boolean chainAnotherbatch = true;

    public void OwnLocalBatchClass(){
    }   

    public Iterable<SObject> start(Database.BatchableContext bc){

        Integer totalCallouts = Limits.getLimitCallouts();

        for(Integer i = 0;i<totalCallouts;i++){
            //Make the callout
            //Build the scope object
            //Have a if condition to set the chainAnotherbatch boolean to true or false.            
        }
        return scope;
    }

    public void execute(Database.BatchableContext bc, List<Sobject> scope){
            Database.insert(scope); 
    }

    public void finish(Database.BatchableContext bc){
        if(chainAnotherbatch){
            Database.executeBatch(new CalloutsFromBatchExample(),1000);
