Clinical Trials Search — ClinicalTrials.gov to JSON

Search ClinicalTrials.gov by condition, drug or sponsor and get trial title, status, phase, sponsor and NCT id as JSON — $0.004 per trial.

Clinical trial activity is a leading signal of pharma and biotech pipelines. This actor turns a condition, drug, or sponsor into the matching registered studies, so healthcare, investment, and competitive-intelligence agents can read the trial landscape as structured data.

What this actor does

• Search ClinicalTrials.gov by condition, intervention/drug, or sponsor
• Each result: brief title, recruitment status, phase, lead sponsor, conditions, NCT id
• Open any study at clinicaltrials.gov/study/{nctId}
• Batch many terms per run; cap spend with maxResults
• Agent-ready: flat JSON with sourceUrl + scrapedAt for citation

You only pay for successful results — failed or empty lookups cost nothing.

Why pick this Actor

• Stable NCT IDs, recruiting status, sponsor, conditions, and phases via the official ClinicalTrials.gov v2 API
• Per-result pricing ($0.004/result) with a hard maxResults spend cap — empty lookups cost $0
• Flat, stable JSON schema with sourceUrl + scrapedAt on every item — citation-ready for RAG and grounding
• Batch many queries in one run; overlapping results are deduplicated and charged once
• MCP server, OpenAPI schema, and LangChain/CrewAI tool support out of the box — no glue code

Sample output

Each dataset item is flat, typed JSON with a sourceUrl and scrapedAt for citation/grounding:

{
  "query": "diabetes",
  "source": "clinical_trials",
  "title": "Effect of Diet on Type 2 Diabetes",
  "status": "COMPLETED",
  "sponsor": "University Hospital",
  "nctId": "NCT00471549",
  "conditions": [
    "Diabetes Mellitus, Type 2"
  ],
  "sourceUrl": "https://clinicaltrials.gov/api/v2/studies?query.term=diabetes",
  "scrapedAt": "2026-06-11T09:00:00.000Z"
}

Input

{"queries":["diabetes"]}

Field	Type	Description
queries / query	array / string	Condition, drug, or sponsor. One or many.
maxResults	integer	Hard spend cap (billed per result).
keywords / postedAfter	filters	Narrow results; enable delta/scheduled runs.

How much does it cost

Pay-per-result: $0.004 per successful result. No subscription, no compute-unit guesswork, no charge for empty results. An orchestrator can cap spend with maxResults.

How to use it with AI agents (MCP), Claude, and the API

Claude Desktop / Claude Code via Apify MCP

{
  "mcpServers": {
    "apify": {
      "command": "npx",
      "args": ["-y", "@apify/actors-mcp-server", "--actors", "oblanceolate_mandola/clinical-trials-search"],
      "env": { "APIFY_TOKEN": "<YOUR_APIFY_TOKEN>" }
    }
  }
}

Python (Apify API)

from apify_client import ApifyClient
client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("oblanceolate_mandola/clinical-trials-search").call(run_input={"queries":["diabetes"]})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

TypeScript (Apify API)

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('oblanceolate_mandola/clinical-trials-search').call({"queries":["diabetes"]});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

LangChain / CrewAI tool

from langchain_apify import ApifyActorsTool
tool = ApifyActorsTool("oblanceolate_mandola/clinical-trials-search")  # agent calls it autonomously

OpenAPI schema for self-integrating GPT agents is auto-exposed at the Actor's API tab.

Data & compliance

Reads only publicly accessible endpoints. No login, no credential harvesting, no CAPTCHA bypass. Every result carries its sourceUrl so downstream agents can cite and re-verify.

FAQ

How do I open a study?

Each result includes its NCT id; the study page is clinicaltrials.gov/study/{nctId}.

Can I track a company’s pipeline?

Yes — search by sponsor name and schedule with postedAfter for new-trial alerts.

What is the source?

The official ClinicalTrials.gov v2 API (US National Library of Medicine).

Can AI agents call this Actor directly?

Yes — via the Apify MCP server (snippet above), the OpenAPI schema on the Actor's API tab, or the LangChain/CrewAI tool wrapper. Results are flat JSON with sourceUrl and scrapedAt on every item, so downstream agents can cite and re-verify.

What happens when there are no results?

You pay nothing. Billing is per dataset item delivered, so an empty lookup costs $0, and the run log states why (no match, source rate limit) instead of failing silently.
