## 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.

# README

## Academic Research & Citation Tracker

An [Apify Actor](https://apify.com/actors) that searches multiple academic databases for research papers matching your keywords and returns structured citation data.

### Features

- **Multi-source search** — queries arXiv, PubMed, and Crossref simultaneously
- **Structured citation output** — title, authors, journal, DOI, abstract, URL, published date
- **Concurrent searching** — parallel queries across sources and keywords
- **Date filtering** — optional date range to find only recent publications
- **Graceful abort** — handles stop signals cleanly to minimize costs
- **Webhook notifications** — optional POST callback when the run completes

### Data Sources

| Source    | Coverage                                                                 |
|-----------|--------------------------------------------------------------------------|
| **arXiv** | Preprints in physics, mathematics, computer science, and related fields |
| **PubMed** | Biomedical literature from MEDLINE, life science journals, and online books |
| **Crossref** | Scholarly publications across all disciplines (DOI registration agency) |

### Input Schema
