Pulsar API for developers

These endpoints are public, need no API key, and send permissive CORS headers, so you can call them straight from a browser, a server or a script. Please be considerate — the link shield is rate-limited per IP.

GET /api/link.php?url=… — is a URL a known scam, malware or phishing link? Checks the same threat intelligence as our on-site tools.

JavaScript
const url = 'https://example.com/some-link';
const r = await fetch('https://astrina.io/api/link.php?url=' + encodeURIComponent(url));
const d = await r.json();
if (d.listed) console.warn('flagged:', d.category, d.sources);
PHP
$url = 'https://example.com/some-link';
$d = json_decode(file_get_contents(
  'https://astrina.io/api/link.php?url=' . urlencode($url)), true);
if ($d['listed']) echo "flagged: {$d['category']}\n";
Python
import requests
d = requests.get('https://astrina.io/api/link.php',
                 params={'url': 'https://example.com/some-link'}).json()
if d['listed']:
    print('flagged:', d['category'], d['sources'])

02Status feed

GET /api/status.php?slug=… — a machine-readable feed of a published status page: each monitored service, its state and how many independent devices confirm it.

JavaScript
const r = await fetch('https://astrina.io/api/status.php?slug=your-status-slug');
const d = await r.json();
if (d.ok) console.log(d.slug, 'monitors:', d.monitors);
PHP
$d = json_decode(file_get_contents(
  'https://astrina.io/api/status.php?slug=your-status-slug'), true);
if ($d['ok']) print_r($d);
Python
import requests
d = requests.get('https://astrina.io/api/status.php',
                 params={'slug': 'your-status-slug'}).json()
print(d)
