When to Use

• AI-powered search — When you need semantic understanding of search queries
• Research — When you need citations and sources for answers
• Content extraction — When you need to scrape content from specific URLs
• Similar page discovery — When you want to find related pages to a given URL
• Category filtering — When searching for specific types: linkedin profile, company, research paper, news, etc.

Best Practices

• Use category filters — The category parameter scopes results to specific types. Use linkedin profile for people searches before enriching with Apollo or Clado.
• Use contents for full text — Search returns highlights; use contents endpoint for full page extraction
• Limit results — Set numResults to control costs (max 100)
• For errors — See @skills/polymer-pay-api-errors/SKILL.md for complete error code reference and troubleshooting
