Error Handling

• 400 - Invalid engine name or missing q parameter
• 401 - Invalid API key
• 429 - Rate limit — wait and retry
• Empty organic_results means no listings found — try broader terms
• Use separate -q flags if & in query string causes issues: -q 'engine=ebay_search' -q 'q=vintage watch'
