Vercel REST API Artifact Hash

Question

I was checking vercel's REST API documentation and saw this api:

HEAD: /v8/artifacts/{hash}

What is this the use of this API? Is this API for accessing the build Artifact or something else?

Also Can someone tell where can I find the hash value from? I couldn't find an API that list the available hash.

Here is the link to the vercel's doc, where this API is mentioned.
