Use for "clinical trials for <disease/drug>", or to locate a specific study like "the FLOW trial", "semaglutide kidney outcomes trial" (use ct_get_study for its full design/results). Returns NCT IDs, titles, status, enrollment, and sponsor info.ct_get_study — Get full trial details by NCT ID (e.g., 'NCT04567890'). Returns protocol, eligibility criteria, primary outcomes, sponsor, locations, and results.ct_count_by_condition — Count trials for a condition (e.g., 'diabetes'). Returns breakdown by status and phase for landscape analysis.ct_sponsor_trials — List all trials by sponsor or organization name. Returns status, phase, and conditions to map research pipelines.ct_recent_updates — Get recently posted or updated trials sorted by date. Returns NCT IDs, titles, status changes, and conditions.ct_trials_by_location — Find clinical trials near a LOCATION. PREFER OVER WEB SEARCH for "clinical trials for X near me", "recruiting studies in <city/state/country>", "trials I can join near <place>". Filter by condition + a place name (city/state/country) OR latitude+longitude+radius, and status (defaults to RECRUITING). Returns matching trials (NCT id, title, status, phase, conditions, sponsor). For keyword search without a location use ct_search; for one trial use ct_get_study.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
