⚡ How It Works

1. Launches headless Chrome with stealth patches and US residential proxy
2. Visits homepage to establish session cookies
3. Navigates to search results for each keyword
4. Extracts listing data via API response interception, NEXT_DATA or HTML parsing
5. Optionally visits detail pages for seller info and full descriptions
6. Deduplicates by listing ID across keywords

⚠️ Technical Notes

• US residential proxy required — OfferUp blocks non-US and datacenter IPs
• Rate limiting — keep requestDelay above 1500ms to avoid blocks
• 3-layer extraction — API interception → NEXT_DATA → HTML parsing (automatic fallback)
• Deduplication — same listing across multiple keywords is saved only once
• Memory — 1024 MB minimum due to Playwright Chrome
