# Vercel Functions

> Use Firecrawl with Vercel Functions to search, scrape, and interact with web data in serverless deployments.

## Prerequisites

* Vercel project (Next.js, SvelteKit, Nuxt, or standalone)
* A Firecrawl API key — [get one free](https://www.firecrawl.dev/app/api-keys)

## Setup

```bash theme={null}
npm install @mendable/firecrawl-js
```

Add `FIRECRAWL_API_KEY` as an environment variable in your Vercel project settings, or in `.env.local` for local development:

```bash theme={null}
FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```

## Search the web

Create `api/search.ts` (or `app/api/search/route.ts` for Next.js):

```typescript theme={null}
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });

export async function POST(request: Request) {
  const { query } = await request.json();
  const results = await firecrawl.search(query, { limit: 5 });

  return new Response(JSON.stringify(results), {
    headers: { "Content-Type": "application/json" },
  });
}
```

## Scrape a page

Create `api/scrape.ts` (or `app/api/scrape/route.ts` for Next.js):

```typescript theme={null}
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });

export async function POST(request: Request) {
  const { url } = await request.json();
  const result = await firecrawl.scrape(url);

  return new Response(JSON.stringify(result), {
    headers: { "Content-Type": "application/json" },
  });
}
```

## Interact with a page

Create `api/interact.ts` (or `app/api/interact/route.ts` for Next.js):

```typescript theme={null}
import Firecrawl from "@mendable/firecrawl-js";

const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });

export async function POST(request: Request) {
  const result = await firecrawl.scrape("https://www.amazon.com", {
    formats: ["markdown"],
  });
  const scrapeId = result.metadata?.scrapeId;

  await firecrawl.interact(scrapeId, {
    prompt: "Search for iPhone 16 Pro Max",
  });
  const response = await firecrawl.interact(scrapeId, {
    prompt: "Click on the first result and tell me the price",
  });

  await firecrawl.stopInteraction(scrapeId);

  return new Response(JSON.stringify({ output: response.output }), {
    headers: { "Content-Type": "application/json" },
  });
}
```

## Deploy

```bash theme={null}
vercel deploy
```

## Test it

```bash theme={null}
curl -X POST https://your-project.vercel.app/api/search \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping"}'
```

<Note>
  Vercel Functions have a default timeout of 10 seconds on the Hobby plan and 60 seconds on Pro. For large crawl jobs, use the Firecrawl async API with webhooks instead.
