Hi @hong, welcome to the Fireblocks community and thanks for sharing your question.
There is an API endpoint you can call to get the list of supported assets
However based on the error message you shared, it appears that the asset you are transferring (XLM_USDC_T_CEKS) is not supported in the destination address.
From first glance it seems that you’ll need to recheck that the destination really supports those assets.
The workspace name
The txId
If it was initiated with an API then provide the 4 first digits of the API key
