How to extract converted leads data

How to extract converted leads data

Hi there, 

I want to extract data automatic from zoho to do some analysis in another program. Now I use the following request URL:  https://crm.zoho.com/crm/private/xml/Leads/getRecords?authtoken= Auth Token &scope=crmapi
to get the leads data. 

Now I want to know when a lead converted to Account/Contact. Is it possible to get that data by a same sort of request URL?   Or is it possible to get a datetime field of the date that a lead was converted to Contact/Account? 

I tried it with the GetCVRecord method, but this isn't working for me, since I have to change the custom View all the time. 

Does anyone know how to get this information? 

Thanks!
