# API Changes The PredictHQ API may change from time to time. Major changes that break backwards compatibility will be introduced with a new version but backwards compatible changes may be introduced at any time without warning. ## Backwards Compatible Changes Examples of some changes we might make that don't break backwards compatibility and may be introduced at any time without warning: * New fields added to API responses * New event categories and labels * New API query parameters * New API endpoints --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.predicthq.com/api/overview/api-changes.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
