## Pricing

from $6.00 / 1,000 lead lookups

This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## 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

## B2B Leads Finder API — Company & Email Discovery

Find company profiles, public contact emails, phones and verified email
candidates from a domain — **no login, no per-lead data provider**.

### What it combines

1. **Company profile** (public LinkedIn page): name, website, industry,
   company size, headquarters, employees, followers.
2. **Website contact scan**: public emails, phone numbers and social links from
   the homepage plus contact/about/team pages.
3. **Email-pattern candidates**: for a person, ranks common corporate patterns
   and checks DNS MX (optional SMTP).

### Endpoints

| Method | Path | Description |
|---|---|---|
| POST | `/find` | Full lookup |
| GET | `/find?domain=...&firstName=...&lastName=...` | Query-string form |
| GET | `/health` | Liveness probe |

```bash
curl -X POST "https://<container-url>/find" \
  -H "Content-Type: application/json" \
  -d '{"domain":"stripe.com","companySlug":"stripe","firstName":"Jane","lastName":"Doe"}'
```

### Output

```json
{
  "company": {"name": "Stripe", "website": "https://stripe.com", "industry": "…", "companySize": "…"},
  "domain": "stripe.com",
  "publicEmails": ["help@stripe.com"],
  "phones": [],
  "socials": {"linkedin": "…", "twitter": "…"},
  "leads": [
    {"email": "jane.doe@stripe.com", "type": "pattern", "confidence": 100, "pattern": "{first}.{last}", "mxFound": true, "smtpAccepts": null, "source": "email-pattern"}
  ],
  "count": 1,
  "warnings": []
}
```

### Notes

- Public emails are only returned if the company publishes them.
- Pattern candidates are ranked by commonness; `smtpAccepts: null` means port 25
  was blocked (the MX verdict still applies).
- No email is ever sent.

# 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 = {
    "proxyUrl": ""
};

// Run the Actor and wait for it to finish
const run = await client.actor("galih_rakasiwi/b2b-leads-finder").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);
});

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 = { "proxyUrl": "" }

# Run the Actor and wait for it to finish
run = client.actor("galih_rakasiwi/b2b-leads-finder").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 '{
  "proxyUrl": ""
}' |
apify call galih_rakasiwi/b2b-leads-finder --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,galih_rakasiwi/b2b-leads-finder"
        }
    }
}
```

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).
