欢迎使用 Firecrawl

Firecrawl 是一个 API 服务，它接受一个 URL，抓取并转换为干净的 markdown。我们会抓取所有可访问的子页面，为您提供每个页面的干净 markdown。无需站点地图。

​
如何使用？

我们提供了易于使用的 API 和托管版本。您可以在 这里 找到游乐场和文档。如果您愿意，也可以自行托管后端。 以下是开始使用的资源： 需要 SDK 或集成？通过打开一个问题让我们知道。 自托管： 要进行自托管，请参考此处的指南。

​
API 密钥

要使用 API，您需要在Firecrawl上注册并获取一个 API 密钥。

​
功能

  • 抓取: 抓取 URL 并以 LLM 准备就绪的格式（markdown、结构化数据通过LLM 提取、截图、html）获取其内容
  • 爬虫: 抓取网页的所有 URL 并返回 LLM 准备就绪的格式的内容
  • 地图: 输入一个网站并获取所有网站 URL - 非常快速
  • 提取: 使用 AI 从单个页面、多个页面或整个网站获取结构化数据。

​
强大的功能

  • LLM 准备就绪的格式: markdown、结构化数据、截图、HTML、链接、元数据
  • 硬核功能: 代理、反机器人机制、动态内容（js 渲染）、输出解析、编排
  • 可定制性: 排除标签、使用自定义头部在认证墙后面爬取、最大爬取深度等…
  • 媒体解析: pdfs、docx、图像。
  • 可靠性第一: 设计用于获取您需要的数据——无论有多难。
  • 操作: 点击、滚动、输入、等待等操作，然后再提取数据
您可以在我们的文档中找到 Firecrawl 的所有功能以及如何使用它们。

​
爬虫

用于抓取一个 URL 及其所有可访问的子页面。这将提交一个爬虫任务并返回一个作业 ID，以便检查爬虫的状态。

​
安装

pip install firecrawl-py

npm install @mendable/firecrawl-js

go get github.com/mendableai/firecrawl-go

# 将以下内容添加到您的Cargo.toml中
[dependencies]
firecrawl = "^1.0"
tokio = { version = "^1", features = ["full"] }

​
使用

from firecrawl import FirecrawlApp

app = FirecrawlApp(api_key="fc-YOUR_API_KEY")

# 爬取一个网站:
crawl_status = app.crawl_url(
  'https://firecrawl.dev',
  params={
    'limit': 100,
    'scrapeOptions': {'formats': ['markdown', 'html']}
  },
  poll_interval=30
)
print(crawl_status)

import FirecrawlApp from '@mendable/firecrawl-js';

const app = new FirecrawlApp({apiKey: "fc-YOUR_API_KEY"});

const crawlResponse = await app.crawlUrl('https://firecrawl.dev', {
  limit: 100,
  scrapeOptions: {
    formats: ['markdown', 'html'],
  }
})

if (!crawlResponse.success) {
  throw new Error(`Failed to crawl: ${crawlResponse.error}`)
}

console.log(crawlResponse)

import (
	"fmt"
	"log"

	"github.com/mendableai/firecrawl-go"
)

func main() {
	// 使用您的 API 密钥初始化 FirecrawlApp
	apiKey := "fc-YOUR_API_KEY"
	apiUrl := "https://api.firecrawl.dev"
	version := "v1"

	app, err := firecrawl.NewFirecrawlApp(apiKey, apiUrl, version)
	if err != nil {
		log.Fatalf("无法初始化 FirecrawlApp: %v", err)
	}

	// 爬取一个网站
	crawlStatus, err := app.CrawlUrl("https://firecrawl.dev", map[string]any{
		"limit": 100,
		"scrapeOptions": map[string]any{
			"formats": []string{"markdown", "html"},
		},
	})
	if err != nil {
		log.Fatalf("发送爬取请求失败: %v", err)
	}

	fmt.Println(crawlStatus) 
}

use firecrawl::{crawl::{CrawlOptions, CrawlScrapeOptions, CrawlScrapeFormats}, FirecrawlApp};

#[tokio::main]
async fn main() {
    // 使用API密钥初始化FirecrawlApp
    let app = FirecrawlApp::new("fc-YOUR_API_KEY").expect("无法初始化FirecrawlApp");

    // 爬取网站
    let crawl_options = CrawlOptions {
        scrape_options: CrawlScrapeOptions {
            formats: vec![CrawlScrapeFormats::Markdown, CrawlScrapeFormats::HTML].into(),
            ..Default::default()
        }.into(),
        limit: 100.into(),
        ..Default::default()
    };

    let crawl_result = app
        .crawl_url("https://mendable.ai", crawl_options)
        .await;

    match crawl_result {
        Ok(data) => println!("爬取结果（使用了{}积分）：
{:#?}", data.credits_used, data.data),
        Err(e) => eprintln!("爬取失败：{}", e),
    }
}

curl -X POST https://api.firecrawl.dev/v1/crawl \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY' \
    -d '{
      "url": "https://docs.firecrawl.dev",
      "limit": 100,
      "scrapeOptions": {
        "formats": ["markdown", "html"]
      }
    }'
如果您使用的是 cURL 或 SDK 上的async crawl函数，这将返回一个ID，您可以使用该 ID 来检查爬虫的状态。 
{
  "success": true,
  "id": "123-456-789",
  "url": "https://api.firecrawl.dev/v1/crawl/123-456-789"
}

​
检查爬虫任务

用于检查爬虫任务的状态并获取其结果。 
crawl_status = app.check_crawl_status("<crawl_id>")
print(crawl_status)

Node;
const crawlResponse = await app.checkCrawlStatus('<crawl_id>');

if (!crawlResponse.success) {
  throw new Error(`Failed to check crawl status: ${crawlResponse.error}`);
}

console.log(crawlResponse);

// 获取爬取状态
crawlStatus, err := app.CheckCrawlStatus("<crawl_id>")

if err != nil {
  log.Fatalf("获取爬取状态失败: %v", err)
}

fmt.Println(crawlStatus)

let crawl_status = app.check_crawl_status(crawl_id).await;

match crawl_status {
    Ok(data) => println!("Crawl Status:\n{:#?}", data),
    Err(e) => eprintln!("Check crawl status failed: {}", e),
}

curl -X GET https://api.firecrawl.dev/v1/crawl/<crawl_id> \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY'

​
响应

根据爬虫的状态，响应将有所不同。对于未完成或超过 10MB 的大响应，会提供next URL 参数。您必须请求此 URL 以检索下一批 10MB 的数据。如果缺少next参数，则表示爬虫数据的结束。

​
抓取

要抓取单个 URL，请使用scrape_url方法。它接受 URL 作为参数并返回抓取的数据作为字典。 
from firecrawl import FirecrawlApp

app = FirecrawlApp(api_key="fc-YOUR_API_KEY")

# 抓取一个网站:
scrape_result = app.scrape_url('firecrawl.dev', params={'formats': ['markdown', 'html']})
print(scrape_result)

import FirecrawlApp, { ScrapeResponse } from '@mendable/firecrawl-js';

const app = new FirecrawlApp({apiKey: "fc-YOUR_API_KEY"});

// 抓取一个网站：
const scrapeResult = await app.scrapeUrl('firecrawl.dev', { formats: ['markdown', 'html'] }) as ScrapeResponse;

if (!scrapeResult.success) {
  throw new Error(`抓取失败: ${scrapeResult.error}`)
}

console.log(scrapeResult)

import (
	"fmt"
	"log"

	"github.com/mendableai/firecrawl-go"
)

func main() {
	// 使用你的API密钥初始化FirecrawlApp
	apiKey := "fc-YOUR_API_KEY"
	apiUrl := "https://api.firecrawl.dev"
	version := "v1"

	app, err := firecrawl.NewFirecrawlApp(apiKey, apiUrl, version)
	if err != nil {
		log.Fatalf("无法初始化FirecrawlApp: %v", err)
	}

	// 抓取一个网站
	scrapeResult, err := app.ScrapeUrl("https://firecrawl.dev", map[string]any{
		"formats": []string{"markdown", "html"},
	})
	if err != nil {
		log.Fatalf("无法抓取URL: %v", err)
	}

	fmt.Println(scrapeResult)
}

使用 firecrawl::{FirecrawlApp, scrape::{ScrapeOptions, ScrapeFormats}};

#[tokio::main]
async fn main() {
    // 使用 API 密钥初始化 FirecrawlApp
    let app = FirecrawlApp::new("fc-YOUR_API_KEY").expect("无法初始化 FirecrawlApp");

    let options = ScrapeOptions {
        formats: vec![ScrapeFormats::Markdown, ScrapeFormats::HTML].into(),
        ..Default::default()
    };

    let scrape_result = app.scrape_url("https://firecrawl.dev", options).await;

    match scrape_result {
        Ok(data) => println!("抓取结果:
{}", data.markdown.unwrap()),
        Err(e) => eprintln!("地图失败: {}", e),
    }
}

curl -X POST https://api.firecrawl.dev/v1/scrape \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY' \
    -d '{
      "url": "https://docs.firecrawl.dev",
      "formats" : ["markdown", "html"]
    }'

​

​
提取

使用 LLM 提取，您可以轻松地从任何 URL 中提取结构化数据。我们支持 pydantic 模式，以便让您更容易使用。以下是如何使用它的方法： v1 目前仅在 node、python 和 cURL 上受支持。 
from firecrawl import FirecrawlApp
from pydantic import BaseModel, Field

# 使用你的API密钥初始化FirecrawlApp
app = FirecrawlApp(api_key='your_api_key')

class ExtractSchema(BaseModel):
    company_mission: str
    supports_sso: bool
    is_open_source: bool
    is_in_yc: bool

data = app.scrape_url('https://docs.firecrawl.dev/', {
    'formats': ['json'],
    'jsonOptions': {
        'schema': ExtractSchema.model_json_schema(),
    }
})
print(data["json"])

import FirecrawlApp from '@mendable/firecrawl-js';
import { z } from 'zod';

const app = new FirecrawlApp({
  apiKey: 'fc-YOUR_API_KEY',
});

// 定义用于提取内容的架构
const schema = z.object({
  company_mission: z.string(),
  supports_sso: z.boolean(),
  is_open_source: z.boolean(),
  is_in_yc: z.boolean(),
});

const scrapeResult = await app.scrapeUrl('https://docs.firecrawl.dev/', {
  formats: ['json'],
  jsonOptions: { schema: schema },
});

if (!scrapeResult.success) {
  throw new Error(`抓取失败: ${scrapeResult.error}`);
}

console.log(scrapeResult.extract);

curl -X POST https://api.firecrawl.dev/v1/scrape \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY' \
    -d '{
      "url": "https://docs.firecrawl.dev/",
      "formats": ["json"],
      "jsonOptions": {
        "schema": {
          "type": "object",
          "properties": {
            "company_mission": {
                      "type": "string"
            },
            "supports_sso": {
                      "type": "boolean"
            },
            "is_open_source": {
                      "type": "boolean"
            },
            "is_in_yc": {
                      "type": "boolean"
            }
          },
          "required": [
            "company_mission",
            "supports_sso",
            "is_open_source",
            "is_in_yc"
          ]
        }
      }
    }'
输出：
JSON
{
    "success": true,
    "data": {
      "json": {
        "company_mission": "训练一个安全的人工智能，利用您的技术资源回答客户和员工的问题，这样您的团队就不必这样做了",
        "supports_sso": true,
        "is_open_source": false,
        "is_in_yc": true
      },

        "sourceURL": "https://docs.firecrawl.dev/"
      },
    }
}

​
无模式提取（新功能）

您现在可以通过仅传递一个prompt到端点来进行无模式提取。llm 选择数据的结构。 
curl -X POST https://api.firecrawl.dev/v1/scrape \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY' \
    -d '{
      "url": "https://docs.firecrawl.dev/",
      "formats": ["json"],
      "jsonOptions": {
        "prompt": "从页面中提取公司使命。"
      }
    }'
输出：
JSON
{
    "success": true,
    "data": {
      "json": {
        "company_mission": "训练一个安全的人工智能，使用您的技术资源回答客户和员工的问题，以便您的团队不必这样做",
      },

使用操作与页面交互

Firecrawl 允许您在抓取网页内容之前对网页执行各种操作。这对于与动态内容交互、浏览页面或访问需要用户互动的内容特别
