Astun have set up a National Address Search web service, which is based on the standard Address Search Request used by iShare.  The National Address Search service has been populated with national coverage of AddressBase® Premium data.  At present it is provided on a beta service.The

This service is hosted by an EC2 Instance using an iShareData Astun database as a Data Share and an osdata database as the source. The data is then scheduled to refreshed refresh at a chosen day and time.

...

https://services.astuntechnology.com/v1/yourcouncil-gov-uk/data/addressbase/locationsearch?

The endpoint will be configured with basic authentication based on those used in the iShare GIS Print to PDF and WPS service requests.

...

Requests are made in the following form (for example searching on the postcode NW1 6XE)

https://go.yourcouncil.gov.uk/nlpgservices.astuntechnology.com/v1/yourcouncil-gov-uk/data/addressbase/locationsearch?pagesize=10&startnum=1&location=NW1%206XE

...

The search algorithm is based on string matching, but with preference given to the postcode substring.  For best results, the full postcode should always be used where possible and known, in combination with another unique element of the address string.  As per the examples below

NOTE: In the above examples, spaces are not necessary in the postcode, and searches with NW16XE will also work.  Results can become a bit more spurious with other spacing.  For example whilst "215 NW1 6XE" identifies the specific property, but "215 NW 16 XE" returns all properties in the postcode.

Where postcode is not known or is only partially known the search engine will aim to identify the best fit possible, as per the examples below.

There is however no further "intelligence" in the search matching.  For example if the search is done on Baker Road London (which does not exist), it would not consider Baker Street to be a better match, but would prefer addresses that included the word "Baker" and "Road" in the address string, as per the example below (which returns multiple other addresses).

There is however no further "intelligence" in the search matching.  For example if the search is done on Baker Road London (which does not exist), it would not consider Baker Street to be a better match, but would prefer addresses that included the word "Baker" and "Road" in the address string, as per the example below (which returns multiple other addresses).
