[pczeglik-iohk]

Small POC of using @cardano-sdk/cardano-services-client for fetching token's metadata

[pczeglik-iohk]

You can use Postman / Insomnia to make requests to Mainnet using settings like below:

url: https://backend.live-mainnet.eks.lw.iog.io/asset/get-asset
method: POST
request body:

{
    "assetId": "29d222ce763455e3d7a09a665ce554f00ac89d2e99a1a83d267170c64d494e",
    "extraData": {
        "tokenMetadata": true
    }
}

To get information about token's decimal notation, we need to add extraData -> "tokenMetadata": true
