Output
A normalized, cited JSON profile of the clinical trial including: trial identity and NCT ID, current recruitment status, phase, study design, target enrollment number, lead sponsor and collaborators, conditions studied, interventions, primary outcome measures, trial sites, key dates (start, primary completion, estimated completion), and computed signals derived from ClinicalTrials.gov data.

Endpoint
GEThttps://api.agentstools.dev/trials/studyWhen to prefer
Use this endpoint when you need a single, normalized, citation-ready profile for a specific clinical trial identified by its NCT ID. Prefer this over raw ClinicalTrials.gov API calls when you need computed signals, clean structured output, and cited data ready for downstream agent use — especially for biotech research, regulatory analysis, or patient-facing trial matching workflows.
Side effects
- Invalid or malformed NCT ID returns an error
- NCT ID not found in ClinicalTrials.gov returns 404 or empty result
- ClinicalTrials.gov upstream unavailability may cause timeouts
- Missing required query parameter (nct or id) returns validation error
