How this service works
Full ClinicalTrials.gov study record by NCT id — the deep detail beyond clinical.trial-search's summary. Returns the brief + detailed description, status, phases, conditions, study design (allocation, intervention model, primary purpose, masking), enrollment, interventions, primary and secondary outcome measures (with time frames), full eligibility criteria (inclusion/exclusion text, sex, age range, healthy-volunteers, standard age groups), lead sponsor and collaborators, all facility locations (name, city, state, country), whether results are posted, and key dates. Free, public-domain (NIH NLM). Use clinical.trial-search to find an NCT id, then this for the complete protocol.
Output
Returns a structured object with comprehensive clinical trial data including: NCT ID, brief and official titles, study status, phases, study type, design details (masking, allocation, intervention model, primary purpose), start and completion dates, enrollment count, lead sponsor, collaborators, list of interventions, conditions studied, eligibility criteria (sex, age ranges, inclusion/exclusion text, healthy volunteers), trial locations (facility, city, state, country), primary and secondary outcomes with timeframes, whether results are available, and last update date. Also includes source metadata referencing ClinicalTrials.gov.

Endpoint
GEThttps://2s.io/api/clinical/study-detailWhen to prefer
Use this endpoint when you need comprehensive, structured detail about a single known clinical trial identified by its NCT ID. Prefer this over search endpoints when you already have the NCT ID and need full study metadata including eligibility, design, outcomes, and locations in one call. Ideal for medical research assistants, patient matching, or regulatory due diligence workflows.
Side effects
- Invalid or non-existent NCT ID returns empty items array or error
- NCT ID format incorrect (must start with NCT followed by digits)
- Trial exists but has no detailed data yet returns partial object
- Network timeout if ClinicalTrials.gov upstream is slow
- Payment failure if USDC balance is insufficient
