# Reveal emails and phone numbers

Reveals the emails and direct and mobile phone numbers of up to 50 contacts found by search, charging only for the fields you ask to reveal.

Pass the contact `id`s from a search and set `reveal` from each result's
`canReveal[].field`. Add up `canReveal[].credits` to know the cost before a
large batch, and check your balance with `account_usage`. Data already
revealed for your account costs nothing to reveal again.

## 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": { "lusha": { "url": "https://mcp.lusha.com" } } }
```

Call the MCP tool `prospecting_contact_enrich`.

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

### API (official)

- Base URL: https://api.lusha.com
- Endpoint: `POST /v3/contacts/enrich`
- Auth: send the header `api_key: $LUSHA_API_KEY`
- Get a key: https://dashboard.lusha.com/enrich/api
- Docs: https://docs.lusha.com/apis/openapi

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.
