 ## API Endpoint Example Calls
 
-These are the possible calls that can be made with [cURL](https://curl.haxx.se/download.html).
-
-```bash
-curl localhost:3000/wallet-balance/eth/
-curl localhost:3000/wallet-balance/ceth/
-curl localhost:3000/supply/eth/9000
-curl localhost:3000/protocol-balance/eth/
-curl localhost:3000/redeem/eth/123
-```
+These are example calls you can make with cURL (https://curl.se/download.html).
 
-Here is an example of outputs for a series of API calls. The wallet started out with 100 ETH.
