v0 by Vercel is an AI tool that generates React UI components from prompts. You can combine it with ScrapeGraphAI to build components that display live data extracted from any website.

​
How it works

v0 generates frontend components. ScrapeGraphAI runs server-side (e.g. in a Next.js API route or Server Action) to avoid exposing your API key and to bypass CORS restrictions.

​
Setup

​
1. Generate your component with v0

Ask v0 to build a component, for example:
Create a card component that displays a company name, description, and founding year fetched from an external API.

​
2. Add a Next.js API route

Install the v2 SDK: 
npm i scrapegraph-js@latest
Create app/api/scrape/route.ts in your Next.js project: 
import { NextRequest, NextResponse } from "next/server";
import { ScrapeGraphAI } from "scrapegraph-js";

const sgai = ScrapeGraphAI(); // reads SGAI_API_KEY from env

export async function POST(req: NextRequest) {
  const { url, prompt } = await req.json();

  const res = await sgai.extract({ url, prompt });

  if (res.status === "success") {
    return NextResponse.json({ data: res.data?.json });
  }
  return NextResponse.json({ error: res.error }, { status: 502 });
}

​
3. Store your API key

Add SGAI_API_KEY to your .env.local file: 
SGAI_API_KEY=your-api-key-here

​
4. Fetch data inside your component

async function getScrapedData(url: string, prompt: string) {
  const res = await fetch("/api/scrape", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ url, prompt }),
  });
  return res.json();
}

​
Tips

  • Use Server Components (async function Page()) or Server Actions to call sgai.extract directly without an API route — the key stays on the server.
  • Pass a schema (JSON Schema or Zod-compiled JSON Schema) to sgai.extract({ url, prompt, schema }) to get typed, structured data back.
Never pass SGAI_API_KEY to a client component. Keep it on the server side.
