# SYNOPSIS
git annex checkpresentkey `key remote`
git annex checkpresentkey `key` `[remote]`
# DESCRIPTION
This plumbing-level command verifies if the specified key's content
is present in the specified remote.
When no remote is specified, it verifies if the key's content is present
somewhere, checking accessible remotes until it finds the content.
Exits 0 if the content is verified present, or 1 if it is verified to not
be present. If there is a problem checking the remote, the special
exit code 100 is used, and an error message is output to stderr.
be present. If there is a problem, the special exit code 100 is used,
and an error message is output to stderr.
# OPTIONS
* `--batch`
Enables batch mode. In this mode, the `key` is not specified at the
command line, but the `remote` may still be. Lines containing keys are
read from stdin, and a line is output with "1" if the key is verified to
be present, and "0" otherwise.

While being asked to check if file is available from "[datalad-archives]" remote I need to check if the archive's key available. Ideally I wish I could ask through the ongoing interaction protocol, but if not, I could use smth like 'git annex checkpresentkey' but that one demands specification also of a remote which to check. In my case I just want to know if that key is available from any remote, so I could confirm that the file is still present in our archives remote, i.e. that it could be retrieved later on

Makes sense, and also I will add a --batch mode to it.
Done.
