ClinicalTrials.gov API.
The platform uses the public ClinicalTrials.gov API as its primary trial source. Each trial record links back to the official ClinicalTrials.gov study page when available.

Transparent limitations of public trial data.
Public trial records may be incomplete, delayed, or changed by the sponsor, site, or registry after Clinical Trial Matcher last refreshed the database. Patients, caregivers, sites, CROs, and sponsors should verify all study status, eligibility, location, compensation, and contact information with the official study listing and participating research site before making decisions.
