## 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`).

Extracts `publication_subdomain`, `publication_url`, `author_name`, `author_handle`, `author_bio`, `author_twitter`, `has_paid_subscriptions`, `avg_reactions`, and `avg_comments` — ideal for newsletter sponsorship outreach and creator B2B lead generation.

#### 1. Clay.com (B2B Enrichment Column)

Use the **Apify** enrichment column or **HTTP API** column in Clay to enrich thousands of rows automatically:

- **Method:** `POST`
- **Endpoint:** `https://api.apify.com/v2/acts/storeintel~substack-newsletter-leads-posts-scraper/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN`
- **JSON Body (with dynamic Clay column mapping):**

```json
{
  "publicationTargets": [
    "{{Substack Subdomain or Domain}}"
  ],
  "scrapePublicationProfiles": true,
  "scrapePosts": true,
  "maxPostsPerPublication": 10,
  "postSortBy": "top"
}
```

#### 2. n8n.io & Make.com Integration

Import the ready-made Blueprint/Workflow JSON above (in Make.com: **Create scenario → More `...` → Import Blueprint**; in n8n: **Import from File/URL**), or add an **Apify — Run an Actor** module pointing to `storeintel/substack-newsletter-leads-posts-scraper` (`dSOldJQGTbikEda10`). Because this Actor uses pure async HTTP/JSON with zero headless browser startup delay, synchronous calls (`run-sync-get-dataset-items`) return structured JSON records in **2–6 seconds**.

## CLI example

```bash
echo '{
  "publicationTargets": [
    "pragmaticengineer",
    "lennysnewsletter"
  ]
}' |
apify call storeintel/substack-newsletter-leads-posts-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,storeintel/substack-newsletter-leads-posts-scraper"
        }
    }
}
```

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).
