The domain to company task returns the company that owns each domain, with name, industry, employee count, location and LinkedIn page, so inbound leads can be sorted by size and industry.

This task needs domains, full website URLs or email addresses from your leads. Each is reduced to its domain and looked up once. Duplicates are skipped.

### How do I run the lead domain lookup automatically?

Run the lead domain lookup task through the Apify API, put it on a schedule in Apify Console, or start it by hand. Export the dataset as CSV or JSON and open it in Google Sheets or Excel.

## 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/b2bdata/company-by-domain.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`).
