## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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.md):

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

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

## 🧬 Clinical Trial Multi-Source Aggregator

> 🚀 **Query 4 medical and clinical data sources in one run.** EU CTIS trials, WHO Disease Outbreaks, openFDA Veterinary Events and NCBI ClinVar variants - aggregated, normalized, pull.

> 🕒 **Last updated:** 2026-05-27 · **📊 10+ fields** per record · **4 sources** · **global clinical, regulatory and genomic intelligence**

The Clinical Trial Multi-Source Aggregator queries four independent medical and clinical data sources in parallel and returns a unified stream of records. Each record is tagged with its source so you can filter, dedupe or split by platform downstream.

The combination spans regulatory clinical trials (EU CTIS), epidemic surveillance (WHO Disease Outbreak News), veterinary pharmacovigilance (openFDA) and genetic variant classifications (NCBI ClinVar).

| 🎯 Target Audience | 💡 Primary Use Cases |
|---|---|
| Pharma, biotech, CROs | Competitive trial intelligence |
| Public health analysts | Outbreak tracking and signal monitoring |
| Genomics researchers | Variant curation and classification |
| Veterinary regulators | Adverse event monitoring |

### 📋 What the Clinical Trial Multi-Source Aggregator does

- Queries up to 4 distinct medical APIs in parallel (`Promise.allSettled`)
- Applies a unified query string across every source that exposes search
- Normalizes every record to the same 10+ field shape
- Returns one tagged stream - `source: ctis | who | openfda | clinvar`
- Continues with the remaining sources if one fails

> 💡 **Why it matters:** one input, one dataset, four authoritative public health and regulatory sources.

### 🎬 Full Demo (_🚧 Coming soon_)

### ⚙️ Input

<table>
<tr><th>Field</th><th>Type</th><th>Required</th><th>Description</th></tr>
<tr><td>query</td><td>string</td><td>no</td><td>Keyword applied to every source that supports search</td></tr>
<tr><td>sources</td><td>array of enum</td><td>no</td><td>Subset of <code>ctis, who, openfda, clinvar</code></td></tr>
<tr><td>maxItems</td><td>integer</td><td>no</td><td>Free 10 / Paid up to 1,000,000</td></tr>
<tr><td>proxyConfiguration</td><td>object</td><td>no</td><td>Apify Proxy (recommended)</td></tr>
</table>

```tabular
{
    "query": "cancer",
    "maxItems": 20,
    "sources": ["ctis", "who", "openfda", "clinvar"]
}
````

```tabular
{
    "query": "BRCA1",
    "maxItems": 10,
    "sources": ["clinvar"]
}
```

> ⚠️ **Good to Know:** each source has its own query semantics. CTIS matches `containAll`. WHO matches `contains(Title)`. openFDA matches against the entire event document. ClinVar defaults to `BRCA1` if no query is supplied.

### 📊 Output

<table>

<tr><td>📌 title</td><td>string</td><td>Record title (trial, outbreak, event or variant)</td></tr>

### ❓ Frequently Asked Questions

**❓ Which sources are queried?** EU CTIS (clinical trials), WHO DON (disease outbreak news), openFDA Animal & Veterinary, NCBI ClinVar.

**❓ Can I pick a subset?** Yes. Pass `sources: ["ctis","who"]` for just two.

**❓ What happens on failure?** Other sources keep running; the failing source emits an error record.

**❓ Is the query applied everywhere?** Yes - adapted to each source's native query syntax.

**❓ How do I dedupe?** Use the `id` + `source` composite as the unique key downstream.

**❓ Do I need API keys?** No. All four sources expose public, unauthenticated endpoints.

**❓ Pricing?** Pay-per-event: billed per record actually pushed.

**❓ What's the maximum?** 1,000,000 items per run for paid users.

**❓ Can I schedule it?** Yes - use Apify Schedules for daily/weekly runs.

**❓ How fresh is the data?** Real-time - each source is queried live on every run.
