Thomas,

I view the balance and credit limit information as separate from the fee 
information supported by draft-ietf-regext-epp-fees.  The balance and credit 
limit information can optionally be returned by draft-ietf-regext-epp-fees, but 
I believe it's better to support a specific query mechanism.  The Balance 
Mapping, which is registered in the EPP Extension Registry 
(https://www.iana.org/assignments/epp-extensions/epp-extensions.xhtml), enables 
querying for the balance and credit limit information directly.  The Low 
Balance Mapping, which is also registered in the EPP Extension Registry, 
supports a poll message when the available credit falls below a pre-defined 
threshold.  Is there interest in these extensions?

    Hello,
    
    some of our registrars keep asking for a feature to simply inquire their
    current account balance and credit limit via EPP.
    
    As far as I can tell, even the latest fee extension draft
    ("draft-ietf-regext-epp-fees-16") only supports the retrieval of this
    information in the response to a *transform* command, but not e.g. in a
    check response.
    
    This isn't ideal since the registrar should not be forced to send a
    "dummy" sequence of billable commands (e.g., a domain create/delete or
    transfer request/cancel sequence) only to get this information.
    Also, even if the registrar would store the values from the most recent
    "non-dummy" transform response, they could become obsolete quickly due to
    intermittent automatic renewals, or account top-up deposits.
    
    What's the opinion in this group regarding the addition of an inquiry
    feature, e.g. by adding a flag to the <domain:check> command fee
    extension, which could trigger the inclusion of the balance/limit in the
    <domain:check> fee response extension?
    
    Best regards,
