Scrape, search, and crawl the web using Firecrawl.

Setup

2. Set the environment variable: export FIRECRAWL_API_KEY=fc-your-key-here
3. Install the SDK: pip3 install firecrawl

Usage

All commands use the bundled fc.py script in this skill's directory.

Get Page as Markdown

Fetch any URL and convert to clean markdown. Handles JavaScript-rendered content.

python3 fc.py markdown "https://example.com"
python3 fc.py markdown "https://example.com" --main-only  # skip nav/footer

Take Screenshot

Capture a full-page screenshot of any URL.

python3 fc.py screenshot "https://example.com" -o screenshot.png

Extract Structured Data

Pull specific fields from a page using a JSON schema.

Schema example (schema.json):

{
  "type": "object",
  "properties": {
    "title": { "type": "string" },
    "price": { "type": "number" },
    "features": { "type": "array", "items": { "type": "string" } }
  }
}

python3 fc.py extract "https://example.com/product" --schema schema.json
python3 fc.py extract "https://example.com/product" --schema schema.json --prompt "Extract the main product details"

Web Search

Search the web and get content from results (may require paid tier).

python3 fc.py search "Python 3.13 new features" --limit 5

Crawl an entire documentation site. Great for learning new frameworks.

Note: Each page costs 1 credit. Set reasonable limits.
