The official JavaScript SDK wraps every endpoint with proper error handling, timeout management, and automatic header injection.

<script src="https://louieauto.com/js/louieauto-sdk.js"></script>

npm install louieauto

// Initialize with your API key
const louie = new LouieAuto({ apiKey: 'your-key-here' });

// Route a lender in 3 lines
const deal = await louie.routeLender({
  beacon: 580,
  down_payment: 1500,
  vehicle_price: 14000,
  vehicle_type: 'car',
  known_issues: ['repo'],
});
console.log(deal.primary.lender); // "Westlake Financial"

// Check stips before you call
const stips = await louie.stipCheck({ lender: 'Westlake', beacon: 580 });
stips.required_stips.forEach(s => console.log(`[${s.priority}] ${s.stip}`));

// True-cost gross calc
const gross = await louie.grossCalc({
  purchase_price: 14000, vehicle_type: 'car', days_on_lot: 12, selling_price: 17500
});
console.log(`${gross.recommendation} — potential gross $${gross.potential_gross}`);

// AI-generated morning briefing
const brief = await louie.getMorningBrief();
console.log(brief.briefing_text);

Error handling: all methods throw LouieAuto.Error with .status and .body properties. Use try/catch or .catch() — no silent failures.
