Note to developers: Search API End of Life
The Search API allows developers to search for resources in the NSDL digital library and build customized search and browse interfaces for a variety of applications. Search queries operate over both the content of the resources and all related metadata including resource-level metadata, annotations, and use data/paradata.
The API is implemented with an instance of the the Digital Discovery System (DDS) repository search server.

The API base URLs is:
