前提条件

​
设置

pip install fastapi uvicorn firecrawl-py
将 API 密钥添加到 .env 中： 
FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​
编写 API

创建 main.py： 
import os
from fastapi import FastAPI
from pydantic import BaseModel
from firecrawl import Firecrawl

app = FastAPI()
firecrawl = Firecrawl(api_key=os.environ["FIRECRAWL_API_KEY"])


class SearchRequest(BaseModel):
    query: str
    limit: int = 5


class ScrapeRequest(BaseModel):
    url: str


class InteractRequest(BaseModel):
    scrape_id: str
    prompt: str


@app.post("/search")
async def search(req: SearchRequest):
    results = firecrawl.search(req.query, limit=req.limit)
    return [{"title": r.title, "url": r.url} for r in results.web]


@app.post("/scrape")
async def scrape(req: ScrapeRequest):
    result = firecrawl.scrape(req.url)
    return {"markdown": result.markdown, "metadata": result.metadata}


@app.post("/interact/start")
async def interact_start(req: ScrapeRequest):
    result = firecrawl.scrape(req.url, formats=["markdown"])
    return {"scrape_id": result.metadata.scrape_id}


@app.post("/interact")
async def interact(req: InteractRequest):
    response = firecrawl.interact(req.scrape_id, prompt=req.prompt)
    return {"output": response.output}


@app.post("/interact/stop")
async def interact_stop(req: InteractRequest):
    firecrawl.stop_interaction(req.scrape_id)
    return {"status": "stopped"}

​
运行

uvicorn main:app --reload

​
试一下

# 进行网页搜索
curl -X POST http://localhost:8000/search \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping", "limit": 5}'

# 抓取页面
curl -X POST http://localhost:8000/scrape \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

# 启动交互会话，然后发送 prompt
curl -X POST http://localhost:8000/interact/start \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.amazon.com"}'
FastAPI 会自动在 http://localhost:8000/docs 生成交互式文档。

​
异步变体

为在高负载下获得更好的并发性能，请使用 AsyncFirecrawl： 
from firecrawl import AsyncFirecrawl

async_firecrawl = AsyncFirecrawl(api_key=os.environ["FIRECRAWL_API_KEY"])

@app.post("/scrape-async")
async def scrape_async(req: ScrapeRequest):
    result = await async_firecrawl.scrape(req.url)
    return {"markdown": result.markdown}
