Ideal for AI agents, SEO tracking, research, and automation, WaterCrawl turns complex data gathering into a seamless experience.


🔍 Web Research Made Effortless: Introducing WaterCrawl

In today's rapidly evolving digital landscape, gathering accurate, timely, and structured information from the web can be challenging. Whether you're building an 🤖 AI-powered research assistant, monitoring your 🧑‍💼 competitors, or simply automating data extraction, traditional scraping methods are cumbersome and brittle. Enter WaterCrawl—a powerful, easy-to-use, self-hosted solution that transforms web scraping and crawling into a streamlined, intuitive experience.


⚙️ Installation Prerequisite

To get started with WaterCrawl, you'll need to install the official Python SDK:

pip install watercrawl

Once installed, you can import and use the WaterCrawlAPIClient in your projects.


💡 Why Choose WaterCrawl?

1. 🧽 Simplified Web Scraping: WaterCrawl allows you to scrape web content effortlessly, converting web pages directly into Markdown, JSON, or PDFs with just one simple API call. No complex pipelines or brittle workflows—just the data you need, instantly.

Example:

from watercrawl import WaterCrawlAPIClient

client = WaterCrawlAPIClient('YOUR_API_KEY')
response = client.scrape_url(
    url="https://watercrawl.dev/",
)

print(response['result']["markdown"])

2. 🕸️ Deep and Customizable Web Crawling: With WaterCrawl, you have granular control over how deeply you crawl, including setting depth limits, filtering by paths or domains, and even rendering JavaScript-heavy pages.

Example:


crawl = client.create_crawl_request(
    url="https://watercrawl.dev",
    spider_options={"max_depth": 2, "page_limit": 10}
)

print(crawl["uuid"])

3. ⚡ Real-time Data Streaming:


for event in client.monitor_crawl_request(crawl["uuid"]):
    if event["type"] == "result":
        print(event["data"]["url"], event["data"]["result"]["markdown"])

Stay informed in real-time. WaterCrawl provides live updates through Server-Sent Events (SSE), perfect for agents or applications requiring real-time data processing.

4. 🏗️ Robust and Scalable: Designed for enterprise-grade applications, WaterCrawl seamlessly handles proxy rotation, JavaScript rendering, and rate-limiting, all wrapped into one efficient framework.


🧠 Simplifying AI Research with Interleaved Thinking

The latest generation of AI research agents, such as Claude 4, leverage interleaved thinking—allowing agents to pause, analyze newly acquired data, and dynamically adapt their next steps. WaterCrawl's real-time scraping and crawling are perfectly suited to empower this adaptive, step-by-step reasoning.

Consider building an "Open Researcher" style agent in just a few lines of code:

from watercrawl import WaterCrawlAPIClient
from anthropic import Anthropic

client = WaterCrawlAPIClient('YOUR_API_KEY')
anthropic_client = Anthropic()

page = client.scrape_url("https://watercrawl.dev/")
response = anthropic_client.messages.create(
    model="claude-4o",
    messages=[
        {"role": "user", "content": f"Summarize this content:\n\n{page['result']['markdown']}"}
    ],
    extra_headers={"interleaved-thinking-2025-05-14": "true"}
)

print(response.content)

📦 Extract Structured Data with Plugins and LLMs

WaterCrawl also supports plugin-based LLM extraction, making it easy to integrate models like GPT-4o-mini directly into your crawl pipeline. You can define a schema and let the model populate structured data such as summaries, metadata, or key-value insights—automatically.

Example:

from watercrawl import WaterCrawlAPIClient

client = WaterCrawlAPIClient(api_key='YOUR_API_KEY', base_url='https://app.watercrawl.dev')

crawl_request = client.scrape_url(
    url='https://watercrawl.dev',
    plugin_options={
        'openai_extract': {
            'is_active': True,
            'llm_model': 'gpt-4o-mini',
            'extractor_schema': {
                '$schema': 'http://json-schema.org/draft-07/schema#',
                'type': 'object',
                'properties': {
                    'summary': {
                        'type': 'string',
                        'description': 'The summary of the page'
                    }
                },
                'required': ['summary']
            },
            'prompt': 'Summarize the web page'
        }
    }
)

print("Extraction complete:", crawl_request['result']['extraction']['summary'])

This method empowers agents and apps to extract rich insights without post-processing—bringing intelligent summarization directly into the crawl layer.
