 The **Speculation Rules API** is designed to improve performance for future navigations. It targets document URLs rather than specific resource files, and so makes sense for multi-page applications (MPAs) rather than single-page applications (SPAs).

 The **`speculationrules`** value of the [`type`](/en-US/docs/Web/HTML/Reference/Elements/script/type) attribute of the [`<script>` element](/en-US/docs/Web/HTML/Reference/Elements/script) indicates that the body of the element contains speculation rules.

 The HTTP **`Sec-Speculation-Tags`** {{Glossary("request header")}} contains one or more `tag` values from the [speculation rules](/en-US/docs/Web/API/Speculation_Rules_API) that resulted in the speculation. This allows a server to identify which rule(s) caused a speculation and potentially block them.

 The HTTP **`Speculation-Rules`** {{Glossary("response header")}} provides one or more URLs pointing to text resources containing speculation rule JSON definitions. When the response is an HTML document, these rules will be added to the document's speculation rule set. See the [Speculation Rules API](/en-US/docs/Web/API/Speculation_Rules_API) for more information.
