Legacy API (Deprecated)

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.

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.
