You can run TokenBalance on your local computer or you can use api.tokenbalance.com to easily parse your erc20 token balances. Connects to your local geth IPC and prints out a simple JSON response for ethereum token balances. Runs on port 8080 by default if you wish to run locally.
You can view the current status of Token Balance along with API latency information on our status page. This status page logs the Ethereum Mainnet, Ropsten testnet, and Rinkeby testnet.

You don't need to compile Token Balance from source anymore! All you need to do is go to Releases in this repo and download the binary that is built for your OS.
Once you've downloaded, rename the file to tokenbalance
for ease if use. On Mac or Linux move this file with the command mv tokenbalance /usr/local/bin/tokenbalance
, you should be able to run the application from anywhere now.
To fetch information about your balance, token details, and ETH balance use the follow API call in a simple HTTP GET or CURL. The response is in JSON so you can easily parse what you need. Replace TOKEN_ADDRESS with the contract address of the ERC20 token, and replace ETH_ADDRESS with your address.

docker run -p 8080:8080 -e GETH_SERVER=https://mainnet.infura.io/APIKEY -d hunterlong/tokenbalance
You can use Token Balance as a typical Go Language package if you you like to implement ERC20 functionality into your own application.
go get github.com/hunterlong/tokenbalance
import (
"github.com/hunterlong/tokenbalance"
)
func main() {
// connect to your Geth Server
configs = &tokenbalance.Config{
GethLocation: "https://eth.coinapp.io",
Logs: true,
}
configs.Connect()
// insert a Token Contract address and Wallet address
contract := "0x86fa049857e0209aa7d9e616f7eb3b3b78ecfdb0"
wallet := "0xbfaa1a1ea534d35199e84859975648b59880f639"
// query the blockchain and wallet details
token, err := tokenbalance.New(contract, wallet)
// Token Balance will respond back useful things
token.BalanceString() // "600000.0"
token.ETHString() // "1.020095885777777767"
token.Name // "OmiseGO"
token.Symbol // "OMG"
token.Decimals // 18
token.Balance // big.Int() (token balance)
token.ETH // big.Int() (ether balance)
