# Build a B2B Lead List - One Row Per Company

**Use case:** 

Build a CRM-ready B2B lead list from any set of company websites. output_mode=summary_only returns one deduplicated row per site with company_name, domain, category, primary_email, emails, email_count, primary_phone and phone_numbers, plus social links like linkedin and facebook. verify_emails adds email_status and deliverable_email_count to flag bad addresses. Export to CSV or your CRM.

## About this Actor

This example demonstrates how to use [Contact Info Scraper](https://apify.com/delicious_zebu/contact-info-scraper.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/delicious_zebu/contact-info-scraper.md

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`).
