Fair use and sources
All data is read live from the official APIs named above and returned without alteration; it is licensed by its publishers under the Open Government Licence or their own API terms, which pass through to you. Companies House data is Crown copyright. Keep calls to what an agent needs; keys that hammer upstream services get throttled so the service stays up for everyone.
