Not able to retrieve account information with valid authorization token

Not able to retrieve account information with valid authorization token

curl -X "GET" " http://mail.zoho.in/api/accounts" -H "Authorization: Bearer <valid authorization token" 
This request gives 301 permanently moved error. I'm trying to get accountID using this API for sending email through api.
Tried both  http://mail.zoho.in/api/accounts and  http://mail.zoho.com/api/accounts. No luck
