Query Parameters for HTML Content

When fetching HTML content (using the .html endpoint), you can control some aspects of how the HTML is generated using query parameters.

For example, usually you will want to make links to other legislation relative to your website. You can do this by using ?resolver=none when fetching the HTML.

Name	Type	Description
coverpage	string	Should the response include a generated coverpage? Use 1 for true, anything else for false. Default: 1. HTML-only.
media-url	string	The fully-qualified URL prefix to use when generating links to embedded media, such as images.
resolver	string	The fully-qualified URL to use when resolving references to other Akoma Ntoso documents. Use no or none to disable. Defaults to using the Laws.Africa resolver.
standalone	number	If this is 1 , the response will be a complete HTML document, including CSS, that can stand on its own. Otherwise it will be an HTML fragment. Default: false. HTML-only.

Expressions at specific points in time

Works may be amended and change over time. You can fetch different amended versions of a work by specifying the language and date in the FRBR URI of the request.

The available points in time of a work are listed in the points_in_time field of the JSON description of the work. Each point in time includes a date and a list of expressions available at that date, one for each available language.

To fetch the very first expression of a work, use frbr-uri/:language@, for example: /akn/za/act/1998/5/eng@.

To fetch a specific point in time, use frbr-uri/:language@:date, for example: /akn/za/act/1998/5/eng@2014-01-17.

To fetch the most recent point in time at or before a specific date, use frbr-uri/:language::date, for example /akn/za/act/1998/5/eng:2014-01-17.

The .format part of the FRBR URI is placed after the @YYYY-MM-DD part.

If you use @ to specify a particular date and the API doesn't have a version at exactly that date, it will return a 404 response. If you need the expression of the work closest to a particular date, use : instead.
