Check ERC-20 Token API

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.

Step 1 : Access Postman

Go to 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.

Step 2 : Execute API and Check the results

From the WEMIX 3.0 API list, select API > Tokens > total-supply to check the ERC-20 token you want.

Check Total Supply for Token{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.
