Using as a Library
import { checkDomain, searchDomains, getStats } from '@aloth/cred1';
// Single lookup
const result = checkDomain('infowars.com');
// { domain: 'infowars.com', score: 0.14, category: 'fake', level: 'low', sources: 2 }
// Not found → null
const unknown = checkDomain('nytimes.com'); // null
// Search
const breitbarts = searchDomains('breit');
// Stats
const stats = getStats();
// { totalDomains: 2673, categories: { unreliable: 2001, fake: 233, ... }, version: '1.0.0' }

Agent Usage Tips
When a user shares a URL or asks about a news source:
- Extract the domain from the URL
- Run
cred1 check <domain> - Interpret the result:
- 🔴 low → warn the user, explain the category (fake/conspiracy)
- 🟡 mixed → note concerns, mention category
- 🟢 ok → confirm generally reliable
- ⚪ neutral → explain absence ≠ trustworthy, advise further checking
For multiple sources in an article or list:
echo -e "domain1.com\ndomain2.com\ndomain3.com" | cred1 batch
For research, combine with stats:
