ClinicalTrials.gov Scraper: Studies, Sponsors, Sites & Contacts

Export clinical trials from the official ClinicalTrials.gov API as clean spreadsheet rows. Search by condition, drug, sponsor, phase, status, study type, dates and site location (city, state, country or a radius around a point), and get titles, phases, conditions, interventions, sponsors and collaborators, key dates, enrollment, eligibility, every site and the contacts sponsors publish for recruitment. One row per study, or one row per study site. $1 per 1,000 records.

What does this ClinicalTrials.gov scraper do?

• Uses the official ClinicalTrials.gov API v2 run by the US National Library of Medicine. No API key, no login, no browser.
• Covers the whole registry: more than 600,000 studies from over 200 countries, refreshed by ClinicalTrials.gov every weekday.
• Filters the way buyers search: condition, intervention or drug, sponsor (lead only or including collaborators), free-text keywords, overall status, phase, study type, results posted, start date range and last-updated date range, NCT IDs.
• Finds trials near a place: site city, state and country, a free-text location, or a geo search (latitude, longitude, radius in miles).
• Sites mode: one row per study site with facility, city, state, ZIP, country, coordinates, site recruitment status and site contacts. Only the sites that match your location and site-status filters are returned, so a search for Boston gives you Boston sites, not all 300 sites of a global trial.
• Pages through any number of results with the API's page tokens and requests only the fields it needs, so runs are fast: the default 50-study run takes about 3 seconds.

Who uses it?

• Pharma, biotech and CRO business development: build lists of active sites, investigators and sponsors by therapeutic area and region for site selection, feasibility and partnership outreach.
• Competitive intelligence: track every trial of a competitor, a drug class or an indication, with phases, timelines and enrollment targets; schedule a weekly run on records updated in the last 7 days.
• Patient recruitment and advocacy: find recruiting trials near a city for a condition, with the published recruitment contacts.
• Investors, analysts and researchers: pipeline mapping, landscape reports and datasets for analysis or AI tools.

How much does it cost?

$1 per 1,000 records ($0.001 per study, or per site in sites mode), plus a $0.00005 start fee per run. You set the maximum, and the run stops when your spending limit is reached.

You collect	You pay
50 recruiting trials for one condition (default run)	$0.05
2,000 recruiting cancer trials worldwide	$2.00
3,000 US cancer trial sites for a site-selection list	$3.00
Weekly update of 500 changed trials in your therapeutic area	about $2 a month

Volume discounts on higher Apify plans. The prices above are for the Apify Free plan. On paid plans the per-record price drops automatically: about 15% lower on Bronze, 25% lower on Silver and 38% lower on Gold and above.

Use it via API, Make, Zapier, n8n or an AI agent

Apify API. Start a run and get the results back in one HTTP request (replace YOUR_API_TOKEN with the token from Apify Console > Settings > Integrations):

curl -X POST "https://api.apify.com/v2/acts/plotpointtech~clinicaltrials-gov-scraper/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"condition": "Melanoma", "status": ["RECRUITING"], "maxResults": 50}'

For longer jobs, start the run asynchronously and read the dataset when it finishes. Official apify-client libraries exist for Python and JavaScript; the API tab on this page has ready-made code.

No-code automation. Connect the tool to Make, Zapier, n8n, Google Sheets, Slack, Airtable or any webhook with Apify integrations, and use Schedules in Apify Console to run it daily or weekly (for example with updatedFrom set to last week).

AI agents (MCP). Give Claude, ChatGPT, Cursor, VS Code or any MCP-compatible agent direct access to this tool through the hosted Apify MCP server. Add this server URL to your client:

https://mcp.apify.com?tools=plotpointtech/clinicaltrials-gov-scraper

The agent can then call the tool with the same input fields shown above and read the results.

FAQ

Is it legal to use ClinicalTrials.gov data? ClinicalTrials.gov is a public US government registry, and the National Library of Medicine offers this API so that anyone can search and download study records. The tool only reads that public API. ClinicalTrials.gov asks users to cite it as the source and to note when the data was retrieved; records are written by the sponsors and investigators, so check important details on the study page (url).

What about the contact names, phones and emails? They are published by sponsors and sites so that patients and referring doctors can ask about enrollment. Use them for that kind of purpose: questions about a study, site feasibility or professional business contact relevant to the trial. Do not use them for unrelated mass marketing, and follow the rules that apply to you, such as GDPR for contacts in the EU and UK, CAN-SPAM for email and TCPA rules for calls and texts in the US. Turn off Include published contacts if you do not need them.

Why does a study appear with only some sites in my city? In studies mode you get the whole study with all its sites. In sites mode you get only the sites that match your city, state, country, radius and site-status filters.

What do the status and phase values mean? They are ClinicalTrials.gov's own codes, for example RECRUITING, ACTIVE_NOT_RECRUITING, PHASE2, NA (not applicable, used for device and behavioral studies). A study can have two phases, such as PHASE1, PHASE2.

Does it include results data? It tells you whether results are posted (hasResults). The detailed results tables are not exported.

How fresh is the data? Every run queries the live API. lastUpdatePostedDate shows when the record last changed.
