Scraping www.zillow.com
www.zillow.com requires JA4 HTTP (Tier 0) because the site uses tls fingerprinting (often cloudflare or similar). Cheaper engine tiers fail; this is the cheapest one that actually works.
Why JA4 HTTP wins on www.zillow.com
Plain `requests`/`fetch` gets blocked because the TLS handshake doesn't look like a real browser. JA4 (via curl_cffi impersonating Chrome 131) makes the handshake match Chrome — Cloudflare passes it through without ever rendering a browser challenge.
Cost math: at 1 credit per request, scraping www.zillow.com costs $0.10–$0.18 per 1,000 requests on the Starter tier. Compare to ScrapingBee ($1.40/1K) or Firecrawl (~$5.33/1K flat). For high-volume workloads on this domain, the credit-based model lands cheaper.
API Discovery: we've captured 1 internal JSON endpoint on this domain during browser scrapes. When you scrape www.zillow.com through DreamScrape, the router checks for these endpoints first and replays them at HTTP speed (1 credit) instead of firing a full browser session. On domains with discovered APIs, this is typically 10× cheaper and 15× faster than the primary tier.
