Wallet APIs enable users to quickly locate ERC-20 tokens by wallet address. Chainbase, Alchemy and Moralis provide APIs to get token-related information.
Finding ERC-20 token balances in any given wallet is simple; when users open their wallets, they automatically display the balances of all the imported tokens. However, when an individual or an entity, such as law enforcement or a business, needs to ascertain the ERC-20 token balances of another address, direct access to the wallet is not possible.
In such cases, an application programming interface (API) can be used to check the balances in a wallet. An API would return all ERC-20 token balances owned by an address and could automate the process of checking token balances.
This article discusses how one can use the APIs of Chainbase, Alchemy and Moralis to get information about ERC-20 tokens owned by an address.
