    --set-env SUBREG_URI=https://soap.subreg.cz/soap \

Tools¶

Read-only: check_domain, info_domain, domains_list, pricelist, get_pricelist, get_credit, users_list, info_user, get_dns_zone, info_contact, contacts_list, info_order, get_tld_info.
Mutating (need SUBREG_READONLY=false): register_domain, renew_domain, delete_domain, add_dns_record, delete_dns_record, create_contact, update_contact, credit_correction.

Warning

Registering, renewing and deleting domains spends credit and affects production names. Never enable writes for an assistant that you would not trust with the registrar account, and try new workflows against a test account first.
