Built-in third party services (Scraperapi, Proxycrawl, Scrapingdog) can work as browser emulators and allow you to bypass IP restrictions, blocks or captchas. Also, these services allow you to extract data from dynamically generated sites with JS rendering (custom parsers may be required). These are paid services, but have free limits. Go to
Affiliate Egg > Settings > Extractorsettings to add your API keys and configure requests for individual domains through these services.
