Extract Webpage Data Agent Skill

Extract Webpage Data

Setup

Read your credentials from ~/.gooseworks/credentials.json:

export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")

If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login

All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"

Extract structured data from any web page using AI. Turn messy HTML into clean, organized data.

When to Use

• User wants to extract specific data from a website
• User asks to scrape information from a page
• User needs structured data from unstructured content
• User wants to pull product info, contact details, etc.
• Converting web content to usable data

  -H "Content-Type: application/json" \
  -d '{"api":"scrapegraph","path":"/v1/smartscraper","body":{"website_url":"https://example.com/products","user_prompt":"Extract all products with name, price, and description"}}'

User: "Scrape the team page and get everyone's info"

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"scrapegraph","path":"/v1/smartscraper","body":{"website_url":"https://example.com/about/team","user_prompt":"Extract team members: name, role, bio, photo URL, LinkedIn"}}'

Error Handling

• 504 - Olostep timeout on slow pages — retry or try a simpler URL
• 400 - Missing required parameters (url_to_scrape for Olostep, website_url + user_prompt for Scrapegraph, url for Riveter)
• Scrapegraph returns error field in response body — check it even on 200 status
• Riveter returns request_status: "error" with details in message
• Some sites block automated scraping — try a different API if one fails

Tips

• Scrapegraph is best for natural language extraction
• Riveter is best when you know the exact schema you want
• Olostep is great for general scraping and AI answers
• For dynamic sites (JavaScript-heavy), these tools handle rendering
• Be specific in your prompts for better extraction results
• Some sites may block automated access
