Vercel Functions
通过 Vercel Functions 在无服务器部署中使用 Firecrawl，以搜索、抓取并与网页数据交互。
- Vercel 项目 (Next.js、SvelteKit、Nuxt 或独立项目)
- 一个 Firecrawl API 密钥 — 免费获取
npm install firecrawl在 Vercel 项目设置中将 FIRECRAWL_API_KEY 添加为环境变量，或在本地开发时将其添加到 .env.local 中：
FIRECRAWL_API_KEY=fc-YOUR-API-KEY创建 api/search.ts (如果使用 Next.js，则为 app/api/search/route.ts) ：
import { Firecrawl } from "firecrawl";
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" },
});
}创建 api/scrape.ts (如果使用 Next.js，则为 app/api/scrape/route.ts) ：
import { Firecrawl } from "firecrawl";
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" },
});
}创建 api/interact.ts (若使用 Next.js，则创建 app/api/interact/route.ts) ：
import { Firecrawl } from "firecrawl";
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" },
});
