## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## PubMed Biomedical Literature Scraper

**PubMed Biomedical Literature Scraper** — a fast, reliable pubmed scraper that needs **no API key**. You pay only for the results you get: failed or empty runs are always free.

This pubmed scraper runs on the [Apify platform](https://apify.com), so you can call it from the API, run it on a schedule, or export results to JSON, CSV, Excel, or Google Sheets.

### What this scraper does

- Extracts structured **pubmed** data with no browser or API key required
- Returns clean JSON, one record per result — ready for sheets, databases, or apps
- Pay-per-result pricing: you are never charged for a run that returns nothing
- Runs on demand or on a schedule, and integrates with 5,000+ apps via the Apify API and webhooks

### What data you get

Each result record includes fields such as:

- **Pmid** (`pmid`) — e.g. `"25315507"`
- **Title** (`title`) — e.g. `"Genome modification by CRISPR/Cas9."`
- **Authors** (`authors`) — e.g. `["Ma Y", "Zhang L", "Huang X"]`
- **Journal** (`journal`) — e.g. `"The FEBS journal"`
- **Source** (`source`) — e.g. `"FEBS J"`
- **Pub Date** (`pubDate`) — e.g. `"2014 Dec"`
- **Epub Date** (`epubDate`) — e.g. `"2014 Nov 7"`
- **Doi** (`doi`) — e.g. `"10.1111/febs.13110"`
- **Volume** (`volume`) — e.g. `"281"`
- **Issue** (`issue`) — e.g. `"23"`
- **Pages** (`pages`) — e.g. `"5186-93"`
- **Issn** (`issn`) — e.g. `"1742-464X"`
- **Pub Types** (`pubTypes`) — e.g. `["Journal Article", "Research Support, Non-U.S. Gov't", "...`
- **Lang** (`lang`) — e.g. `["eng"]`

### Input

| Field | Type | Description |
|---|---|---|
| `searchTerms` | array | PubMed search queries. Each term is searched separately and produces its own results. Supports full PubMed ... |
| `maxResults` | integer | Maximum number of articles to return per search term. Capped at 200. |
| `sort` | string | How PubMed orders the matched articles. |
| `apiKey` | string | Optional free NCBI E-utilities API key. Raises the rate limit from ~3 to ~10 requests/second. Create one at... |

}
```

### Use cases

- Automate research and data collection
- Feed dashboards, sheets, and databases
- Enrich records in your CRM or app
- Monitor changes on a schedule

### Run it as a monitor (alerts on new pubmed)

Schedule this pubmed scraper to run automatically — hourly, daily, or on any cron schedule — with the built-in [Apify Scheduler](https://docs.apify.com/platform/schedules), and have results pushed to you by **webhook, email, Slack, or your own app** the moment they're ready. It's the easiest way to **monitor pubmed for changes over time** and get alerted the instant something new appears — no manual runs. Because pricing is per result, a scheduled monitor only ever charges you for the data each run actually returns.

### Pricing

This actor uses **pay-per-result** pricing at **$0.0006 per record**. There is no monthly fee and no start fee — and **empty or failed runs cost $0**, so you only ever pay for data you actually receive.

### Frequently asked questions

**Do I need an API key or account for the source?** No. This pubmed scraper works out of the box with no API key required.

**What happens if a run returns no results?** You are not charged. Billing is per result, so empty or failed runs are free.

**Can I run the pubmed scraper on a schedule?** Yes. Use the Apify Scheduler to run it hourly, daily, or on any cron schedule, and get results by webhook or API.

**What export formats are supported?** Results can be exported as JSON, CSV, Excel, HTML, or pushed to Google Sheets, a database, or your own app via the Apify API.

**Is the data structured?** Yes. Every pubmed result is a clean, flat JSON record you can use immediately.

# Actor input Schema

## `searchTerms` (type: `array`):

PubMed search queries. Each term is searched separately and produces its own results. Supports full PubMed query syntax, e.g. "crispr", "cancer immunotherapy", "asthma\[Title]", "covid-19 AND vaccine".

## `maxResults` (type: `integer`):

Maximum number of articles to return per search term. Capped at 200.

## `sort` (type: `string`):

How PubMed orders the matched articles.

## `apiKey` (type: `string`):

Optional free NCBI E-utilities API key. Raises the rate limit from ~3 to ~10 requests/second. Create one at https://www.ncbi.nlm.nih.gov/account/settings/ (leave blank to run keyless).

## `maxCostUsd` (type: `integer`):

HARD budget cap. The run stops cleanly before exceeding this.

## `proxyConfiguration` (type: `object`):

This is an open API; no proxy needed. Default is fine.

## Actor input object example

```json
{
  "searchTerms": [
    "crispr"
  ],
  "maxResults": 25,
  "sort": "relevance",
  "proxyConfiguration": {
    "useApifyProxy": false
  }
}
```

  ],

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,chrisp1211/pubmed-scraper-max"
        }
    }
}

```

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).
