URL with value/balance of the coin only API/ for CMC

Hello Guys
I need some help:
I need to create or provide a URL link with balance of the assets (based on STELLAR LUMENS blockchain) -but only a value for coinmarketcap listing.

According the mail:
"3. Can you please show us an API endpoint that specifically displays only the Total Supply on the block explorer in real time as a numerical value? Please provide this as a URL that displays JUST THE VALUE, as it would be easier for our team to integrate.

EG. One could find the total supply of GRS Groestlecoin by querying the following URL: http://chainz.cryptoid.info/grs/api.dws?q=totalcoins

As you can see in the link above, only the value (73215698.88736623) is displayed. Please provide a similar link. If you do not currently have such a link, kindly build one."

Could some one help me to make it ? We got Stellar Blockchain
