Read the published key and (by default) prove it still works.
Tries each source in turn and, within a source, each key-shaped candidate,
returning the first the live API accepts. Throws rather than returning a
placeholder when no source is reachable, none states a key, or none states
one the API accepts — so a caller never proceeds with a value that cannot
authenticate.
