Note: this is using v0 version of the Firecrawl API which is being deprecated. We recommend switching to v1.

​
Installation

To install the Firecrawl Rust SDK, add the following to your Cargo.toml: 
[dependencies]
firecrawl = "^0.1"
tokio = { version = "^1", features = ["full"] }
serde = { version = "^1.0", features = ["derive"] }
serde_json = "^1.0"
uuid = { version = "^1.10", features = ["v4"] }

[build-dependencies]
tokio = { version = "1", features = ["full"] }

​
Usage

  1. Get an API key from firecrawl.dev
  2. Set the API key as an environment variable named FIRECRAWL_API_KEY or pass it as a parameter to the FirecrawlApp struct.
Here’s an example of how to use the SDK in Rust: 
use firecrawl::FirecrawlApp;

#[tokio::main]
async fn main() {
  let api_key = "YOUR_API_KEY";
  let api_url = "https://api.firecrawl.dev";
  let app = FirecrawlApp::new(api_key, api_url).expect("Failed to initialize FirecrawlApp");

  // Scrape a single URL
  let scrape_result = app.scrape_url("https://docs.firecrawl.dev", None).await;
  match scrape_result {
    Ok(data) => println!("Scraped Data: {}", data),
    Err(e) => eprintln!("Error occurred while scraping: {}", e),
  }
  // Crawl a website
  let crawl_params = json!({
    "pageOptions": {
      "onlyMainContent": true
    }
  });

  let crawl_result = app.crawl_url("https://docs.firecrawl.dev", Some(crawl_params)).await;
  
  match crawl_result {
    Ok(data) => println!("Crawl Result: {}", data),
    Err(e) => eprintln!("Error occurred while crawling: {}", e),
  }
}

​
Scraping a URL

To scrape a single URL with error handling, use the scrape_url method. It takes the URL as a parameter and returns the scraped data as a serde_json::Value. 
let scrape_result = app.scrape_url("https://docs.firecrawl.dev", None).await;

match scrape_result {
  Ok(data) => println!("Scraped Data: {}", data),
  Err(e) => eprintln!("Failed to scrape URL: {}", e),
}

​
Crawling a Website

To crawl a website, use the crawl_url method. It takes the starting URL and optional parameters as arguments. The params argument allows you to specify additional options for the crawl job, such as the maximum number of pages to crawl, allowed domains, and the output format. 
let crawl_params = json!({
  "crawlerOptions": {
    "excludes": ["blog/"],
    "includes": [], // leave empty for all pages
    "limit": 1000
  },
  "pageOptions": {
    "onlyMainContent": true
  }
});
let crawl_result = app.crawl_url("https://docs.firecrawl.dev", Some(crawl_params)).await;

match crawl_result {
  Ok(data) => println!("Crawl Result: {}", data),
  Err(e) => eprintln!("Failed to crawl URL: {}", e),
}

​
Checking Crawl Status

To check the status of a crawl job, use the check_crawl_status method. It takes the job ID as a parameter and returns the current status of the crawl job. 
let job_id = "your_job_id_here";
let status = app.check_crawl_status(job_id).await;

match status {
  Ok(data) => println!("Crawl Status: {}", data),
  Err(e) => eprintln!("Failed to check crawl status: {}", e),
}

​
Canceling a Crawl Job

To cancel a crawl job, use the cancel_crawl_job method. It takes the job ID as a parameter and returns the cancellation status of the crawl job. 
let job_id = "your_job_id_here";
let canceled = app.cancel_crawl_job(job_id).await;

match canceled {
  Ok(status) => println!("Cancellation Status: {}", status),
  Err(e) => eprintln!("Failed to cancel crawl job: {}", e),
}

​
Extracting structured data from a URL

With LLM extraction, you can easily extract structured data from any URL. Here is how you to use it: 
let json_schema = json!({
  "type": "object",
  "properties": {
    "top": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
        "title": {"type": "string"},
        "points": {"type": "number"},
        "by": {"type": "string"},
        "commentsURL": {"type": "string"}
      },
      "required": ["title", "points", "by", "commentsURL"]
      },
      "minItems": 5,
      "maxItems": 5,
      "description": "Top 5 stories on Hacker News"
    }
  },
  "required": ["top"]
});

let llm_extraction_params = json!({
  "extractorOptions": {
    "extractionSchema": json_schema
  }
});

let scrape_result = app.scrape_url("https://news.ycombinator.com", Some(llm_extraction_params)).await;

match scrape_result {
  Ok(data) => println!("LLM Extraction Result: {}", data),
  Err(e) => eprintln!("Failed to perform LLM extraction: {}", e),
}

​
Search for a query

To search the web, get the most relevant results, scrape each page and return the markdown, use the search method. The method takes the query as a parameter and returns the search results. 
let query = "What is firecrawl?";
let search_result = app.search(query).await;

match search_result {
  Ok(data) => println!("Search Result: {}", data),
  Err(e) => eprintln!("Failed to search: {}", e),
}

​
Error Handling

The SDK handles errors returned by the Firecrawl API and raises appropriate exceptions. If an error occurs during a request, an exception will be raised with a descriptive error message.
