echo -e "rt.com\ninfowars.com\nnytimes.com" | cred1 batch
# 🟡  rt.com                                    0.105  unreliable   mixed
# 🔴  infowars.com                              0.140  fake         low
# ⚪  nytimes.com                               ?      unknown      neutral

# JSON array output:
echo -e "rt.com\ninfowars.com" | cred1 batch --json

Useful for processing lists from files:

cat my-sources.txt | cred1 batch

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:

1. Extract the domain from the URL
2. Run cred1 check <domain>
3. 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:
