python scripts/find_emails.py --from-file page.md
```

**Arguments:**

| Argument          | Description                                          |

| `-j`, `--json`    | JSON output (`{"emails": {"email": ["path", ...]}}`) |

| `-v`, `--verbose` | Verbose crawl output                                 |

**Output format (human-readable):**

Emails are grouped by domain. Clear structure for multi-URL runs:

```
Found 3 unique email(s) across 2 domain(s)

## example.com

  • contact@example.com
    Found on: /contact, /about
  • support@example.com
    Found on: /support

## other.com

  • info@other.com
    Found on: /contact-us
```

**Output format (JSON):**

LLM-friendly structure with summary and per-domain breakdown:

```json
{
  "summary": {
    "domains_crawled": 2,
    "total_unique_emails": 3
  },
  "emails_by_domain": {
    "example.com": {
      "emails": {
        "contact@example.com": ["/contact", "/about"],
        "support@example.com": ["/support"]
      },
      "count": 2
    },
    "other.com": {
      "emails": {
        "info@other.com": ["/contact-us"]
      },
      "count": 1
    }
  }
}
```

## Configuration

Edit `scripts/url_patterns.json` to customize which URLs the crawler follows. Only links matching these glob-style patterns are included:

```json
{
  "url_patterns": [
    "*contact*",
    "*support*",
    "*about*",
    "*team*",
    "*email*",
    "*reach*",
    "*staff*",
    "*inquiry*",
    "*enquir*",
    "*get-in-touch*",
    "*contact-us*",
    "*about-us*"
  ]
}
```

If the file is missing or invalid, default patterns are used.

---

## Workflow

1. **Crawl** a site:

   ```bash
   python scripts/find_emails.py https://example.com -o emails.json
   ```

2. **Extract from local file** (e.g., cached markdown):

   ```bash
   python scripts/find_emails.py --from-file crawled.md -j
   ```

3. **Customize** URL filters by editing `scripts/url_patterns.json`.

---

## Dependencies

```bash
pip install crawl4ai
playwright install
```

Requires a browser (Playwright) for local crawling.

---

## Batch Processing

```bash
# Crawl multiple sites – results grouped by domain for clear attribution
python scripts/find_emails.py https://site1.com https://site2.com -j -o combined.json

# Extract from multiple local files
for f in crawled/*.md; do
  echo "=== $f ==="
  python scripts/find_emails.py --from-file "$f" -q
done
```

Multiple URLs are fully supported; output clearly associates each email with its source domain. Domains are normalized (e.g. `www.techbullion.com` and `techbullion.com` merge into one) so duplicate sites are not listed separately.
