# Entity Versioning The Sway Charts REST API supports the notion of *entity versions*. Each business entity (such as an account) has a version which is a number that increases monotonically with any changes. It is possible to find out the order of updates by comparing versions: most recent entity’s version will be the greatest. --- # 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://sway-technologies.gitbook.io/sway-charts-api-documentation/rest-api-specification/getting-started/entity-versioning.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.
