ClinicalTrials.gov Scraper — Bulk trial data, structured JSON, no API key, fully filterable

Search and extract clinical trial records straight from the official ClinicalTrials.gov API v2 and get back clean, structured JSON — trial IDs, titles, status, phases, conditions, interventions, sponsors, enrollment, eligibility, outcomes and study locations. Search by condition, drug, sponsor or free text, filter by recruitment status, and collect thousands of trials per term. No account, no API key. Built for pharma, biotech, CRO and academic teams who need trial data at scale without wrestling with pagination or rate limits.

Features

• 🔎 Multi-term search — pass any number of queries (condition, drug/intervention, sponsor or free text) and the scraper runs each one, deduping trials that appear under several terms by nctId.
• 🎯 Status filtering — narrow results with statuses such as RECRUITING, COMPLETED, ACTIVE_NOT_RECRUITING, TERMINATED or NOT_YET_RECRUITING; leave empty for all.
• 📊 Deep trial detail — phases, study type, enrollment count and type, eligibility (sex, age range, healthy volunteers) and primary outcome measures in every record.
• 🏥 Study locations — toggle includeLocations to attach facility, city, state and country for each site (up to 100 per trial), plus a locationCount.
• 🏢 Sponsor intelligence — lead sponsor, sponsor class and full collaborator list for every trial.
• 📈 Scales cleanly — set maxResultsPerQuery up to 10,000; the API is cursor-paginated and retried automatically on transient errors.
• 🧾 Analysis-ready JSON — flat, predictable fields with direct study URLs, ideal for spreadsheets, databases or dashboards.

What you get

  "maxResultsPerQuery": 100,
  "includeLocations": true
}

Field	Description
queries	Search terms — condition, drug/intervention, sponsor or free text. One run per term.
statuses	Optional status filter (e.g. RECRUITING, COMPLETED). Empty means all statuses.
maxResultsPerQuery	Maximum trials to collect per search term (1–10,000).
includeLocations	Include each trial's study sites (facility, city, state, country).

Use cases

• Build a competitive landscape of trials for a drug, target or indication across sponsors and phases.
• Feed recruiting-trial data (with locations) into patient-matching or site-selection workflows.
• Track sponsor and collaborator activity in a therapeutic area over time.
• Assemble structured trial datasets for market research, due diligence or academic meta-analysis.

Pay-per-event: you're billed a small amount per run and per item scraped — you only pay for what you get. See the Pricing tab for current rates.

FAQ

Do I need an API key? No. This Actor uses the official ClinicalTrials.gov API v2 with no account, login or API key required.

How many trials can I scrape per run? Up to 10,000 trials per query via maxResultsPerQuery, and you can pass multiple queries in one run, so a single run can collect many thousands of trials (deduped by nctId).

Is scraping ClinicalTrials.gov legal? Yes. ClinicalTrials.gov is a public registry, and this Actor reads only its openly available records through the official API v2 and returns them as-is.

What format is the output? Structured JSON — one flat record per trial — exportable as JSON, CSV or Excel. Each record includes NCT ID, titles, status, phases, conditions, interventions, sponsors, enrollment, eligibility, primary outcomes and (optionally) study locations.

Can I filter by recruitment status or include locations? Yes. Use statuses to keep only trials that are RECRUITING, COMPLETED, TERMINATED etc. (leave empty for all), and toggle includeLocations to attach each trial's facility, city, state and country.
