"description": "The UTS API is intended for application developers to perform Web service calls and retrieve UMLS data within their own applications. The UTS API provides the ability to search, retrieve, and filter terms, concepts, attributes, relations, metadata and more from over 160 vocabularies of the UMLS Metathesaurus, as well as the Semantic Network. Paging, sorting and filtering (PSF) capabilities allows users to customize results of Web service calls in many ways: choose to include or exclude specific criteria, sort results by fields, or specify results displayed per page. The documentation provides a suite of Web Services Description Language (WSDL) files, API installation instructions, and sample code.",
