Use this demonstration interface to build a Service List Registry query. View the generated request and explore the example response below.


Only nationally regulated services





The parameter values and responses returned and any visual representations are for demonstration purposes only and do not imply the participation, registration or availability of specific services.


The https secure protocol must be used for all queries to provide privacy and security by automatically encrypting every request and response over a secure connection.


The host or server name used here is for demonstration purposes only. Other subdomain names may also be used for preview and test purposes to provide separation from live services.


Multiple parameters may be provided in a query, presented in the specified order. Where a parameter is not included in the query, the response will include results matching any or no value for that parameter.


Multiple values may be provided for a parameter, presented in alphabetic or numeric order, with the parameter repeated followed by square brackets to indicate that they represent array values. The response will combine matches to any of the values provided and will also include results with no specified value for that parameter.


All query parameters and values are case sensitive and will be compared accordingly by the server. The capitalisation used here is defined by specification and alternative forms may produce errors or unintended responses.


The response can be explored in a List or in a formatted Code view, together with the relevant Headers. The full raw response code can also be viewed in a new browser window.


The status of the response will be returned with an HTTP response status code in the header.

  • 200 OK is returned with a response list for a successful request.
  • 404 Not Found means that no matching services were found.
  • 400 Bad Request indicates that the query was not correctly formed.
