You can query the ERC-20 Token API using Postman.
Let's proceed with the API inquiry process in the order below.
Step 1 : Access Postman
Step 2 : Execute API and Check the results
All examples are based on WEMIX3.0 Testnet.
Go to https://www.postman.com/ and install Postman. After accessing Postman, move to 'Workspaces'.
Select the 'Import' button to insert the WEMIX3.0 API.json file to launch the WEMIX3.0 API.
From the WEMIX 3.0 API list, select API > Tokens > total-supply to check the ERC-20 token you want.
https://explorerapi.test.wemix.com/v1/tokens/{contract_address}/total-supply
Enter the URI above in the input box next to 'Get'.
You can enter the contract address you want in the {contract_address} of the URI.
The figure below is an example of checking the Testnet ERC-20 token.
If you select 'Send', you can see that the output is the same as the data found in Testnet Explorer.
