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 Company & Decision Maker Lead Finder — MX-Verified Apollo Alternative (MCP Ready)

Extract **MX-verified B2B company leads, executive email permutations, role inboxes, career page links, and web tech stacks** directly from company domains — with **zero LinkedIn/Apollo cookie bans** and **zero charge for dead domains**.

***

### Use Cases

- **Cookie-Free Apollo / ZoomInfo Alternative:** Generate verified company profiles and executive email candidates (`{first}.{last}@domain`, `{first}@domain`, `{f}{last}@domain`) directly from live company websites and DNS `MX` records.
- **Decision-Maker Email Permutation:** Pass a list of target domains and executive names (`{ domain, fullName, role }`) to automatically infer the company's email naming pattern and verify domain mail server readiness.
- **Dead-Domain Filtering:** Automatically skips defunct websites that have no DNS `MX` records and no active emails — saving your outbound budget and protecting sender reputation.
- **AI SDR Agent Tool (`/mcp`):** Built-in Apify Standby Mode (`/mcp`) lets autonomous AI sales agents enrich accounts and generate decision-maker contact candidates in `< 2 seconds`.

### Data Privacy & Responsible Use

- **Public Corporate Signals Only:** This Actor analyzes public company websites and public DNS `MX` records and generates algorithmic business email candidates from user-supplied contact names. It does not scrape private social network databases.
- **Compliance:** Always adhere to GDPR, CCPA, and CAN-SPAM requirements when conducting B2B outreach.

***

### FAQ & Support

- **Am I charged if a domain is offline or has no MX record?** No. `@fleet/ppe-guard` validates that a domain has either active `MX` records or discovered emails before charging `result-item`.
- **Support & Issues:** Open an issue on the Apify Store **Issues** tab for support.

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).
