# Firecrawl Python SDK
The Firecrawl Python SDK is a library that allows you to easily scrape and crawl websites, and output the data in a format ready for use with language models (LLMs). It provides a simple and intuitive interface for interacting with the Firecrawl API.
## Installation
To install the Firecrawl Python SDK, you can use pip:
```bash
pip install firecrawl-py
```
## Usage
1. Get an API key from [firecrawl.dev](https://firecrawl.dev)
2. Set the API key as an environment variable named `FIRECRAWL_API_KEY` or pass it as a parameter to the `FirecrawlApp` class.
Here's an example of how to use the SDK:
```python
from firecrawl.firecrawl import FirecrawlApp
app = FirecrawlApp(api_key="fc-YOUR_API_KEY")
# Scrape a website:
scrape_status = app.scrape_url(
'https://firecrawl.dev',
params={'formats': ['markdown', 'html']}
)
print(scrape_status)
# Crawl a website:
crawl_status = app.crawl_url(
'https://firecrawl.dev',
params={
'limit': 100,
'scrapeOptions': {'formats': ['markdown', 'html']}
},
wait_until_done=True,
poll_interval=30
)
print(crawl_status)
```
### Scraping a URL
To scrape a single URL, use the `scrape_url` method. It takes the URL as a parameter and returns the scraped data as a dictionary.
```python
url = 'https://example.com'
scraped_data = app.scrape_url(url)
```
### Extracting structured data from a URL
With LLM extraction, you can easily extract structured data from any URL. We support pydantic schemas to make it easier for you too. Here is how you to use it:
```python
class ArticleSchema(BaseModel):
title: str
points: int
by: str
commentsURL: str
class TopArticlesSchema(BaseModel):
top: List[ArticleSchema] = Field(..., max_items=5, description="Top 5 stories")
data = app.scrape_url('https://news.ycombinator.com', {
'extractorOptions': {
'extractionSchema': TopArticlesSchema.model_json_schema(),
'mode': 'llm-extraction'
},
'pageOptions':{
'onlyMainContent': True
}
})
print(data["llm_extraction"])
```
### 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.
```python
idempotency_key = str(uuid.uuid4()) # optional idempotency key
crawl_result = app.crawl_url('firecrawl.dev', {'excludePaths': ['blog/*']}, 2, idempotency_key)
print(crawl_result)
```
### Asynchronous Crawl a Website
To crawl a website asynchronously, use the `async_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.
```python
crawl_result = app.async_crawl_url('firecrawl.dev', {'excludePaths': ['blog/*']}, "")
print(crawl_result)
```
### 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.
```python
id = crawl_result['id']
status = app.check_crawl_status(id)
```
### Map a Website
Use `map_url` to generate a list of URLs from a website. The `params` argument let you customize the mapping process, including options to exclude subdomains or to utilize the sitemap.
```python
# Map a website:
map_result = app.map_url('https://example.com')
print(map_result)
```
### Crawl a website with WebSockets
To crawl a website with WebSockets, use the `crawl_url_and_watch` 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.
```python
# inside an async function...
nest_asyncio.apply()
# Define event handlers
def on_document(detail):
print("DOC", detail)
def on_error(detail):
print("ERR", detail['error'])
def on_done(detail):
print("DONE", detail['status'])
# Function to start the crawl and watch process
async def start_crawl_and_watch():
# Initiate the crawl job and get the watcher
watcher = app.crawl_url_and_watch('firecrawl.dev', { 'excludePaths': ['blog/*'], 'limit': 5 })
# Add event listeners
watcher.add_event_listener("document", on_document)
watcher.add_event_listener("error", on_error)
watcher.add_event_listener("done", on_done)
# Start the watcher
await watcher.connect()
# Run the event loop
await start_crawl_and_watch()
```
## 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.
## Running the Tests with Pytest
To ensure the functionality of the Firecrawl Python SDK, we have included end-to-end tests using `pytest`. These tests cover various aspects of the SDK, including URL scraping, web searching, and website crawling.
### Running the Tests
To run the tests, execute the following commands:
Install pytest:
```bash
pip install pytest
```
Run:
```bash
pytest firecrawl/__tests__/e2e_withAuth/test.py
```
