# Search companies

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

Search costs no credits and needs at least one filter. Resolve filter values
such as industries and metro areas with the lookup tool first, then enrich the
companies you keep for their full profile.

## 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, 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: OAuth; sign in when the agent asks
- Docs: https://docs.gtm.ai/reference/api-overview

Before doing anything else, make one read-only call to confirm access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data.
- Never print API keys.
