Checksum files in Raw repository


I am working with a raw repository on Nexus OSS 3.29.0-02 and trying to get the checksum of specific file by the using of API:


if the ${FILE} is on the root of the repo it works fine, but in case the file I am looking for is into a deeper level (folder1/folder2), I am not able to ask the info about the specific file.

If the file request is :
The API reports all artefacts from /folder1/

How can I use the API to get the checksum of a file at specific path in raw repository?

Please, could you help me ?
