nginx won't restart with my config file - api

Question

Restarting nginx :
# service nginx start
Starting nginx: nginx: [emerg] duplicate upstream "api" in /etc/nginx/sites-enabled/default:1
nginx: configuration file /etc/nginx/nginx.conf test failed
This is the config file :
upstream api{

}
Do you see any problem ?
