ClinicalTrials.gov Classic API

The Classic API is the legacy ClinicalTrials.gov interface that preceded the Data API v2 and exposes full-study, brief-study, and field-values endpoints with XML, JSON, and CSV responses. It is being deprecated in favor of the v2 REST API and remains online for backward compatibility while consumers migrate.
