If a wiki is set to read only mode, this information should be available via the api. I suggest to include the read-only message as specified via $wgReadOnly or $wgReadOnlyFile in the information returned by a meta=siteinfo query.

Can this also be applied to errors encountered when performing an action? For example, on action=edit:
{ "code": "readonly", "info": "The wiki is currently in read-only mode" }
to something exposing wfReadOnlyReason(), eg:
{ "code": "readonly", "info": "The wiki is currently in read-only mode (reason: blah blah blah)" }
