# Legacy API (Deprecated)

> Reference for deprecated Sunbird AI endpoints

<Warning>
  The endpoints in this version are **deprecated**. They continue to work for now but return `Deprecation` and `Sunset` response headers and will be removed in a future release. New integrations should use the current **v2 · Latest** API.
</Warning>

This section documents the older Sunbird AI endpoints for reference while you migrate. Switch to **v2 · Latest** using the version dropdown at the top of the sidebar.
