# Look up a company (`lookup_company`)

What a company is, from its domain: what it does, where, its size, its site's technologies, shared mailboxes and social profiles; never people.

What a company is, from its domain: name, description, location, industries, size, funding, languages, the technologies its site uses, its shared mailboxes (info@, sales@ ...) and phone numbers, and its social profiles. From Conecto's index of public company facts, else from its own homepage. Never people. The business's Conecto inboxes never write first to a mailbox found here. $0.05 when found; free when nothing is known.

Price: $0.05 a call. A call that fails costs nothing.

## Use it when

Before a first call or email with a company, or to fill in a CRM company.

- For news and pages about the company, use [web_search](https://conecto.chat/tools/web/web_search.md).

## Say this to your agent

> Before I call Hotel Elbblick tomorrow, what do we know about them? Their site is hotel-elbblick.example.

| Name | Type | Required | Description | Allowed values | Default |
|---|---|---|---|---|---|
| `domain` | string | yes | The company's web address, e.g. hansenvoss.example. 4 to 253 characters. |  |  |
