The versioned API allows you to combine and perform several types of search operations to programmatically retrieve results. Check out the API documentation which provides guidelines for getting you started and details the request/response schema with examples of supported query types and code snippets based on beta testing by our pilot users. A Swagger UI is also provided for quick and easy query development.
