## 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`).

# README

## DevTools, AI SDK & Open-Source Publisher Leads (Direct Emails + Velocity)

Extract verified **AI Agent Builders, DevTools Companies, SaaS SDK Publishers, and Technical Founders** from the official **NPM Registry** in under 1 second (`256 MB` RAM)—complete with **Direct Human Maintainer Emails (`primaryEmail` & `maintainerEmails`)**, **Corporate Homepage Domains (`homepageDomain`)**, **GitHub Repository URLs**, and **Monthly Download Velocity (`monthlyDownloads`)**.

# Actor input Schema

## `searchQuery` (type: `string`):

Keywords to target specific ecosystems (e.g., 'langchain ai agent', 'mcp server', 'stripe billing sdk', 'supabase auth', 'nextjs analytics').

## `minMonthlyDownloads` (type: `integer`):

Filter for real adoption by requiring at least this many monthly downloads.

## `requireVerifiedEmail` (type: `boolean`):

Only return records that include at least one direct non-bot maintainer/publisher email address.

## `maxItems` (type: `integer`):

Maximum number of DevTools/SDK publisher leads to return (Free users preview up to 25 leads; paying users unlock up to 10,000 leads per run).

## Actor input object example

```json
{
  "searchQuery": "ai agent mcp sdk",
  "minMonthlyDownloads": 100,
  "requireVerifiedEmail": true,
  "maxItems": 25
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "searchQuery": "ai agent mcp sdk"
};

// Run the Actor and wait for it to finish
const run = await client.actor("zinjaink/npm-devtools-and-sdk-publisher-leads").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "searchQuery": "ai agent mcp sdk" }

# Run the Actor and wait for it to finish
run = client.actor("zinjaink/npm-devtools-and-sdk-publisher-leads").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "searchQuery": "ai agent mcp sdk"
}' |
apify call zinjaink/npm-devtools-and-sdk-publisher-leads --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,zinjaink/npm-devtools-and-sdk-publisher-leads"
        }
    }
}
```

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).
