# Search companies

Returns companies that match industry, location, employee count, revenue, funding and other firmographic filters, with name, website, location, revenue and employee count.

Note: Needs at least one filter, and costs no credits. Resolve filter values such as industries and metro areas with the lookup tool first.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "zoominfo": { "url": "https://mcp.zoominfo.com/mcp" } } }
```

Call the MCP tool `search_companies`.

Server URL: https://mcp.zoominfo.com/mcp

### CLI (official)

Install the command and sign in with it, then confirm it runs.

```sh
brew install zoominfo/gtm-ai/gtm-ai-cli
gtm --version
```

Run `gtm companies search`.

### API (official)

- Base URL: https://api.zoominfo.com/gtm
- Endpoint: `POST /data/v1/companies/search`
- Auth: an OAuth access token, sent as `Authorization: Bearer <token>`
- Docs: https://docs.gtm.ai/reference/api-overview

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
