Token History API

This page explains the concept and features of Token History API.

When you are using Klaytn with your own node, you have to go through all the transactions in order to find token history and other information. Using KAS can spare you of all that time and effort, namely with Token History API. With Token History API, you can easily retrieve the history of a given token. KLAY transaction history, token information for FT, NFT, and MT are also available. The main features of Token History API are:

Get Contract Information

The process of making token contracts trackable with Token History API is called labelling, whereby the contract information is registered on KAS. The labelling status will be returned when you retrieve contract information. You can also specify a certain contract to retrieve its information.

Get Token Information

Retrieve token information. There are different endpoints depending on what you want to search. If you want to see the ownership change of a given token, use Get Token Information. But to find out which tokens an account holds, use Get Token Information by Account.

Get Ownership Information

Retrieve ownership information for NFTs or MTs. Ownership information of MTs shows you the previous owner along with other information. Ownership information of NFTs returns the sender (from), recipient (to) as well as the timestamp of transaction.

Get Token Transaction History

Retrieve token transactions. Pass the following item in the request schema and send a request to the endpoint. It returns token type, transaction and contract information, the sender, and recipient.

• Preset

  Collection of token contract and account addresses. You have to create a Preset on KAS Console Service > Token History > Preset in advance to use this.
