# Introduction

The APIs and associated services are provided by the FAIR Data Informatics Laboratory at the University of California, San Diego.

* Metadata Search via Elasticsearch
  * Resource Information Network (Research Resource Identifiers - RRIDs)
  * SPARC Datasets
* InterLex Terminology
  * Search via Elasticsearch
* Knowledge Graph Services (Coming Soon to the API Gateway)
