Quicknode API suite makes the lives of web3 developers easy, NFT API makes building an NFT application breezy. Today we are thrilled to share our brand new Token API, which makes working with ERC20 tokens super easy. Sign up now!

トークンAPIとは何ですか？

Quicknode Token API is a new RPC API that lets users get ERC20 token data from the Ethereum Mainnet. With Token API, a user can get token metadata, balances, and transfer histories of ERC20 tokens for a wallet; no need for querying smart contracts and/or writing specialized scripts! With Token API, these operations are possible with a single line of code. In the next section, we will see the specific Token API methods and how they work.

トークン API メソッド

• Get Metadata of a specific ERC20 token (qn_getTokenMetadataByContractAddress)Using this method, a user can get metadata of a specific ERC20 token using its contract address.
  

• Look up ERC20 Tokens by symbol (qn_getTokenMetadataBySymbol)Using this method, a user can get ERC-20 token metadata by the token symbol (SHIB, USDT, etc)
  

• Get tokens and their balances for a wallet (qn_getWalletTokenBalance)Using this method, a user can get all the tokens a wallet holds - along with balances.
  

• Get the transfer history of a token for a wallet (qn_getWalletTokenTransactions)Using this method, a user can get transfer histories of a token within a wallet

Token APIはなぜ役立つのでしょうか？

Working with token data can be hectic. There are so many tokens! To get information about each token, one would have to interact with smart contracts, scrape data from the blockchain, and then parse the raw data manually. This process is very much doable, but is very time-consuming and requires processing millions (even billions!) of rows of parsed data given the number of tokens and blocks. Instead, one can use Quicknode Token API for immediate access to this data, with no indexing required!

始める準備はできましたか？

Token API is available & included with all new Ethereum Mainnet endpoints, created after July 25th, 2022 (read more about our new plans here).

For existing Ethereum Mainnet accounts (created before July 25th, 2022), go to the Billing section of your endpoint, locate 'Token API' and click on the blue button saying 'Add to endpoint'.
