## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## ClinicalTrials.gov Scraper — Studies & Trials

Search and extract clinical trial data from **ClinicalTrials.gov** — the US National Library
of Medicine's registry of 500,000+ studies. Filter by condition, intervention, sponsor,
keyword or recruitment status, and get clean structured data per study.

Built on the official ClinicalTrials.gov **v2 API** — free, public, no key, no anti-bot.

### Who it's for

- **Pharma & biotech competitive intelligence** — track trials by drug, sponsor or indication.
- **CROs** — site selection, enrollment and status monitoring.
- **Investors & analysts** — follow pipeline progress and phase transitions.
- **Researchers & AI pipelines** — structured trial metadata at scale.

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `condition` | string | — | Condition/disease, e.g. `diabetes` |
| `intervention` | string | — | Drug/treatment, e.g. `semaglutide` |
| `sponsor` | string | — | Lead sponsor/collaborator, e.g. `Pfizer` |
| `searchTerm` | string | — | Free-text search across fields |
| `status` | array | — | Filter by status: `RECRUITING`, `ACTIVE_NOT_RECRUITING`, `COMPLETED`, `TERMINATED`, … |
| `maxResults` | integer | `200` | Cap on studies returned |

Provide at least one of `condition`, `intervention`, `sponsor` or `searchTerm`.

### Output

One row per study:

```json
{
  "nctId": "NCT07091500",
  "title": "GLP-1 Receptor Agonist for Obesity",
  "status": "RECRUITING",
  "phases": ["PHASE2"],
  "studyType": "INTERVENTIONAL",
  "enrollment": 40,
  "startDate": "2026-01-15",
  "completionDate": "2027-06-30",
  "lastUpdateDate": "2026-07-01",

}
````

### Notes & limits

- Official ClinicalTrials.gov v2 API — free, public, no key or anti-bot; paginated automatically.
- For advanced field-level queries, use the `searchTerm` field (supports the API's expression
  syntax) alongside `condition`/`intervention`/`sponsor`.
- Public data; you are responsible for compliant use of the output.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "condition": "diabetes"
};

// Run the Actor and wait for it to finish
const run = await client.actor("ponderable_hydrometer/clinicaltrials-scraper").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "condition": "diabetes" }

# Run the Actor and wait for it to finish
run = client.actor("ponderable_hydrometer/clinicaltrials-scraper").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
