ClinicalTrials.gov Studies Search (API v2)

Search clinical trials by condition, intervention, sponsor, location and status: phases, enrollment, dates, sponsor class, collaborators, interventions, results flag, countries and summary. Bulk NCT lookup.

Why this actor

• $1/1k vs $12/1k incumbents; official v2 API.
• Pay only for results: $1.00 per 1,000 studys, no start fee, failed lookups are free.
• Robust: automatic retries with exponential backoff, respects Retry-After, per-item error rows instead of crashed runs.
• Clean, flat JSON/CSV/Excel output ready for Google Sheets, Make, Zapier, n8n, Clay, or the Apify API.

Use cases

• Pharma competitive intelligence
• Patient-recruitment and site-selection research
• Investor biotech pipeline tracking
• Medical writing
