ClinicalTrials.gov Scraper — Trials, Sponsors, Sites & Investigators API

Search and export clinical study records from the official ClinicalTrials.gov API — the US National Library of Medicine's registry of clinical trials worldwide. Get the NCT number, title, status, phase, study type, enrollment, conditions, interventions, lead sponsor and sponsor class, central contacts (phone + email), overall officials, and every study site with its principal investigators. Filter by condition, intervention, sponsor, location, recruitment status, phase, study type, and sponsor class, then download clean JSON, CSV, or Excel.

This Actor reads the official ClinicalTrials.gov API v2 (clinicaltrials.gov/api/v2) — no login, no API key — and returns flattened, normalized records instead of the registry's deeply nested JSON. Most "clinical trials" scrapers either dump the raw nested payload or stop at the summary; this one extracts the parts that matter for outreach and intelligence — sponsor, site facilities, and named principal investigators with their contact details — into flat fields you can filter and merge.

What data do you get?

One result per clinical study:

Field	Example
nctId / studyUrl	NCT06739122 + direct study link
title / officialTitle / acronym	Brief and official titles
status / whyStopped	RECRUITING, COMPLETED, TERMINATED...
studyType / phases	INTERVENTIONAL / ["PHASE3"]
enrollmentCount / enrollmentType	55 / ESTIMATED
conditions / interventions	["Type 2 Diabetes"] / drug & device list
leadSponsor / leadSponsorClass	Eli Lilly and Company / INDUSTRY
collaborators	Collaborating organizations
centralContacts	Name, role, phone, email for study contacts
overallOfficials	Study directors / principal investigators
locations	Every site: facility, city, state, ZIP, country, status, principal investigators
eligibility	Sex, age range, healthy-volunteers flag, age groups
firstPostedDate / lastUpdatePostedDate	Registry dates

Use cases

• Pharma & biotech competitive intelligence — track every trial a competitor sponsors by condition, phase, and status; monitor the pipeline in your therapeutic area (sponsorClasses: ["INDUSTRY"]).
• Site selection & CRO business development — find active sites and named principal investigators for a given condition and geography; build investigator target lists with facility contacts.
• Patient recruitment — surface RECRUITING trials for a condition near a location, with central-contact phone and email for referral.
• KOL & investigator mapping — extract principal investigators and study directors across a disease area for medical-affairs and advisory-board outreach.
• Market & landscape research — quantify trial activity by sponsor, phase, enrollment, and region for diligence or strategy.
• AI agents / MCP — a clean, filterable interface to the global trial registry for agent-driven research and enrichment.

How to use it

Every recruiting, industry-sponsored cancer trial with a site in Texas:

{
    "condition": "cancer",
    "state": "Texas",
    "statuses": ["RECRUITING"],
    "sponsorClasses": ["INDUSTRY"],
    "maxResults": 500
}

Every Phase 3 diabetes trial currently recruiting:

{
    "condition": "diabetes",
    "statuses": ["RECRUITING"],
    "phases": ["PHASE3"],
    "maxResults": 500
}

Filters: condition, intervention, sponsor, locationTerm, searchTerm, statuses (recruiting, completed, terminated...), phases (early phase 1 → phase 4), studyType, sponsorClasses (industry, NIH, federal...), state, country, maxResults. At least one narrowing criterion is required.

Data source & freshness

Every run queries the official ClinicalTrials.gov API v2 live. ClinicalTrials.gov is maintained by the US National Library of Medicine (NIH) and updated continuously as sponsors submit and revise records — you get whatever the registry has at the moment of your call. Because it reads the official structured API rather than scraping a website, it does not break the way HTML scrapers do; the v2 API has been stable since its 2024 launch.

Pricing

This Actor uses pay per result: you are charged one study-record event per study returned, and only for records actually delivered. Suggested price $0.003 per record ($3.00 / 1,000 studies).

Why this price: clinical-trials competitors on the store either hide their pricing or use clunky multi-event models — one leading incumbent charges a $0.10 actor-start fee plus $0.01 per search operation. At $0.003 per delivered record with no start fee, this Actor is dramatically cheaper for real extraction while returning richer records (sponsor, every site, and named investigators flattened out). Start low; you only pay for the studies you keep.

Why this Actor

• Official NIH/NLM API v2, no key — no login, no scraping, no anti-bot arms race.
• Investigators & site contacts extracted — principal investigators, facilities, and central contacts pulled into flat fields, not buried in nested JSON.
• Sponsor-class & phase filtering — isolate industry-sponsored pipelines or a specific phase in one call.
• Pay only for results, transparent per-record pricing, JSON/CSV/Excel export, and an MCP-ready interface for AI agents.
