### Lookup Domain Registration (`lookup_domain`)

Inspect a domain with standards-based RDAP lookup and automatic WHOIS fallback. Returns registration status, availability signal, registrar details, nameservers, and lifecycle dates.

**Parameters:**

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `domain` | string | Yes | Domain to inspect (e.g. "example.com") |
| `include_raw` | boolean | No | Include raw RDAP/WHOIS payloads in the output for debugging [default: false] |

**Returns:** Structured domain registration intelligence with registrar, lifecycle dates, status, nameservers, and source/fallback metadata

**Examples:**

*Lookup registration metadata for google.com:*

```json
{
  "domain": "google.com"
}
```

*Lookup openai.com and include raw provider payloads:*

```json
{
  "domain": "openai.com",
  "include_raw": true
}
```

## Frequently Asked Questions

### What registration details can I see?

You can look up registrant data, creation and expiry dates, registrar details, nameservers, and registry status.

### Why does it mention RDAP and WHOIS?

It uses RDAP first and falls back to WHOIS when needed, which improves coverage across different TLDs.

### Can it help with domain investigations?

Yes. It is useful when you need ownership and lifecycle details for security investigations or brand protection.

### Can it tell me when a domain is about to expire?

Yes. Expiry date is one of the main fields returned by the lookup.
