Frequently Asked Questions

How do I handle ZenRows' premium_proxy=true?

In Scrapfly, use proxy_pool="public_residential_pool" instead of a boolean flag:

# ZenRows
premium_proxy = "true"

# Scrapfly
proxy_pool = "public_residential_pool"  # For residential proxies

What if I'm using ZenRows' CSS extractor?

Scrapfly's Extraction API is more powerful:

  • Template extraction: Similar to ZenRows CSS extractor, but more flexible
  • Auto-extraction: Automatically detect and extract common data types
  • LLM extraction: Use natural language prompts for complex extraction

Do I need to change my session management?

ZenRows uses session_id, Scrapfly uses session. The functionality is the same:

# ZenRows
session_id = "my-session"

# Scrapfly
session = "my-session"
