Every business wants more leads.
But the real challenge isn't generating them—it's identifying which leads deserve your team's attention first.
Instead of manually reviewing every inquiry, we can build a simple AI-powered API that analyzes incoming leads and assigns a priority score automatically.
In this article, I'll show a lightweight production-ready approach using Next.js 15 and Gemini 3.5 Flash.
Project Structure

├── api/
│ └── qualify/
│ └── route.ts
├── lib/
│ └── gemini.ts
└── page.tsx
API Route
import { NextResponse } from "next/server";
export async function POST(req: Request) {
const { company, message } = await req.json();
const prompt = `
Company: ${company}
Message:
${message}
Give:
- Score (1-100)
- Priority
- Reason
`;
// Call Gemini API here
return NextResponse.json({
success: true,
score: 92,
priority: "High"
});
}
Example Response
{
"score": 92,
"priority": "High",
"reason": "Large company with a clear automation requirement."
}
Now your CRM, chatbot, or automation workflow can instantly decide which leads should be contacted first.
Why This Matters
A simple AI scoring layer can help teams:
Reduce manual lead review
Respond faster to high-value prospects
Prioritize enterprise customers
Improve sales efficiency
Save hours every week
The best part is that this API can be connected to forms, chatbots, CRMs, or n8n workflows without changing your existing process.
Production Tips
Before deploying this to production, make sure you:
Validate incoming requests
Store API keys securely
Add rate limiting
Log AI responses for monitoring
Cache repeated requests where appropriate
Small improvements like these make a huge difference once traffic starts growing.
Final Thoughts
AI shouldn't replace your sales team—it should remove repetitive work so they can focus on conversations that actually matter.
A lightweight lead qualification API is one of the fastest AI features you can add to an existing product, and it scales well as your business grows.
