## 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

## Article Summarizer (Claude)

> Pass any URL or text — get back a tight summary in your chosen style (**TL;DR / bullets / executive / tweet**) plus topic tags + sentiment. Article body auto-extracted via trafilatura. **BYO Anthropic API key. $0.005 per summary.**

***

### Input Parameters

| Parameter | Type | Default | Description |
|---|---|---|---|
| `url` | string | ``| URL of the article (used if 'text' is empty). |
| `text` | string |`` | Pass article text directly to skip URL fetch. |
| `style` | string | `both` | Output format. |
| `maxWords` | integer | `250` | Soft cap on summary length. |
| `language` | string | `en` | ISO code or language name (e.g. en, ko, es, French). |
| `extractTopics` | boolean | `true` | Append a JSON block with 3-5 topic tags + sentiment. |
| `model` | string | `claude-opus-4-7` | Claude model to use. Opus is highest-quality; Haiku is fastest/cheapes |
| `anthropicApiKey` | string | `—` | Get one at console.anthropic.com. Saved encrypted by Apify. |
| `userAgent` | string | \`\` | Custom UA. |

***

### Why this exists

Summarizing 50 articles a day by hand is dead time. Hiring a summarization SaaS (e.g. Lex.page, Glasp, Summari) costs $20-100/month per seat. This actor wraps trafilatura (article extraction) + Claude (summarization) in one call:

1. URL → clean article body (no nav, ads, comments)
2. Body → Claude with your chosen output style
3. Optional: topic tags + sentiment

You pay Apify $0.005 per summary; Anthropic bills you for tokens (typically $0.001-0.01 per summary at Opus 4.7 prices).

### Setting your Anthropic API key

You can:

1. **Paste in input** — secure (marked `isSecret`, encrypted at rest, hidden in logs)
2. **Save as Apify Task** — input including key is saved, click to re-run
3. **Account-level Secret** — register `MY_ANTHROPIC_KEY` in Apify Integrations, reference as `@MY_ANTHROPIC_KEY` in task input

Get a key at [console.anthropic.com](https://console.anthropic.com).

***

### Pricing

**Pay-Per-Event**: `$0.005 per article` (Apify-side).

Anthropic charges separately for tokens. Typical totals:

| Article length | Input tokens | Anthropic cost (Opus 4.7) | Total |
|---|---|---|---|
| 1K words | ~1300 | ~$0.007 | $0.012 |
| 3K words | ~4000 | ~$0.020 | $0.025 |
| 8K words | ~10500 | ~$0.053 | $0.058 |

Use Sonnet (~5x cheaper) or Haiku (~10x cheaper) for cost savings.

### Use cases

2. **Research aggregation** — Build a topic-tagged knowledge base
3. **Slack/Discord digests** — Daily summary of #blog-feed channel
4. **Personal read-it-later** — Long articles → 30-second TL;DR

## MCP server setup

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).
