```php
use JeffersonGoncalves\SsrfGuard\SsrfGuard;
use JeffersonGoncalves\SsrfGuard\Exceptions\BlockedHostException;

try {
    $response = app(SsrfGuard::class)->safeGet($untrustedUrl);

    $body = $response->body();

### SSRF Guard Pest Tests

Source: https://github.com/jeffersongoncalves/laravel-ssrf-guard/blob/master/resources/boost/skills/ssrf-guard-development/SKILL.md

Pest test cases for the SSRF guard, covering blocking of loopback, private, link-local addresses, non-http schemes, and successful resolution of public IPs. Includes a test for `safeGet` throwing a `BlockedHostException` on private hosts.

```php
use JeffersonGoncalves\SsrfGuard\SsrfGuard;
use JeffersonGoncalves\SsrfGuard\Exceptions\BlockedHostException;

beforeEach(fn () => $this->guard = new SsrfGuard);

it('blocks loopback / private / link-local', function () {
    expect($this->guard->isPublicUrl('http://127.0.0.1'))->toBeFalse();
    expect($this->guard->isPublicUrl('http://10.0.0.1'))->toBeFalse();
    expect($this->guard->isPublicUrl('http://169.254.169.254'))->toBeFalse();
});

it('blocks non-http schemes', function () {
    expect($this->guard->isPublicUrl('ftp://1.1.1.1'))->toBeFalse();
});

it('allows and pins a public IP', function () {
    expect($this->guard->resolveEntries('http://1.1.1.1'))->toBe(['1.1.1.1:80:1.1.1.1']);
});

it('throws on safeGet to a private host', function () {
    $this->guard->safeGet('http://127.0.0.1');
})->throws(BlockedHostException::class);
```

--------------------------------

### Check URL safety with isPublicUrl

Source: https://github.com/jeffersongoncalves/laravel-ssrf-guard/blob/master/README.md

Check whether a URL is safe to fetch. Returns true for public URLs, false for loopback, private, link-local, or disallowed schemes.

```php
use JeffersonGoncalves\SsrfGuard\SsrfGuard;

$guard = app(SsrfGuard::class);

$guard->isPublicUrl('https://example.com');     // true
$guard->isPublicUrl('http://127.0.0.1');        // false (loopback)
$guard->isPublicUrl('http://10.0.0.1');         // false (private)
$guard->isPublicUrl('http://169.254.169.254');  // false (link-local / metadata)
$guard->isPublicUrl('ftp://example.com');       // false (scheme not allowed)
```

--------------------------------

### Validate user input with isPublicUrl

Source: https://github.com/jeffersongoncalves/laravel-ssrf-guard/blob/master/README.md

Validate user input before storing or fetching it. Aborts with 422 if the URL is not public.

    abort(422, 'The URL must point to a public host.');
}
