Need an API to get a transaction which used the specific asset.

I want to find users who have used a specific list of assets.
To do this, I need an API returning transfer asset transactions of which the input is in the list of specific tackers.

No files, tests, or entry points are named in the issue. First clarify the intended API input and the meaning of “specific tackers,” then identify the existing transaction-query entry point; the work is done when the API reliably returns transfer asset transactions matching the requested asset list.
