# Person Enrichment From Email Waterfall

> Hydrate person and company context from a known email using a provider waterfall. Use it to pilot, verify output, and scale safely.

In Claude Code, type:

```
/deepline-gtm I have a list of emails in contacts.csv. Enrich each one with name, title, company, and LinkedIn URL.
```

```
/deepline-gtm Look up jane@acme.com and get me their full profile — name, title, company, LinkedIn
```

<Accordion title="CLI command">
  ```bash theme={null}
  deepline tools execute crustdata_enrich_contact \
    --payload '{"email":"jane@acme.com"}'
  ```
</Accordion>

## How It Works

Providers are tried left to right. The first one to return a result wins — the rest are skipped.

## Parameters

| Name    | Type     | Required | Description          |
| ------- | -------- | -------- | -------------------- |
| `email` | `string` | Yes      | Known email address. |

## Cost

**0-3.21 credits** — waterfalls stop at the first match, so you only pay for the provider that returns a result.

| --------------- | ----------- |
| Hunter          | 0.3         |
| Crustdata       | 1.2         |
| Prospeo         | 0.6         |
