## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Clinical Trials Search: ClinicalTrials.gov Studies & Sponsors

Search 500,000+ ClinicalTrials.gov studies. Provide at least one of condition, drug/intervention or keyword; optionally filter by recruitment status. Returns NCT ID, title, phase, status, sponsor, enrollment, dates, countries and link. Free official API, no key.

### What does Clinical Trials Search do?

Search ClinicalTrials.gov by condition, drug and status: phases, sponsors, enrollment, dates and countries.

### What can you use it for?

- Find every recruiting trial for a disease or drug.
- Track competitor pipelines by sponsor, phase and status.
- Build datasets for pharma market research or systematic reviews.
- Monitor newly registered studies on a schedule.

### Why use this Actor?

- **Fast and cheap:** lightweight HTTP-based Actor with no browser, so runs finish in seconds and cost very little.
- **No API keys or accounts needed** for the data source (see notes below).
- **Clean, structured JSON** that you can export as CSV, Excel, JSON or XML, or pull through the Apify API and integrations.
- **Scheduling, webhooks and integrations:** run it daily and send results to Google Sheets, Slack, Zapier, Make, n8n or your own API.

### Input

Configure the run in the **Input** tab (all fields have sensible defaults).

| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| `condition` | string | no | - | For example: diabetes, breast cancer, long covid. |
| `intervention` | string | no | - | For example: metformin, pembrolizumab, exercise. |
| `term` | string | no | - | Free-text search across all study fields. |
| `statuses` | array of strings | no | - | Only studies with one of these statuses (empty = all). |
| `maxResults` | integer | no | `30` | Maximum number of studies to return. |

#### Example input

```json
{
  "condition": "diabetes",
  "maxResults": 30
}
```

### How much does it cost?

The Actor is billed by Apify according to the pricing shown on the **Pricing** tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

### Notes and limitations

- Data comes from the official ClinicalTrials.gov API v2 (US National Library of Medicine, public domain).
- Fill in at least one of condition, intervention or keyword; combine them to narrow the search.

### Tips

- Start with a small test run, then scale up the input.
- Use **Schedules** to automate recurring runs and **Webhooks** or **Integrations** to deliver the data where you need it.
- Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

### FAQ

**Is this medical advice?**

No. It only lists registered studies. Talk to a doctor before making medical decisions.

### Feedback

Found a bug or need an extra field? Open an issue from the **Issues** tab of this Actor and it will be looked at quickly.

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
