Specialized endpoints cover web, news, image, and video search categories with independent access methods for each.

Rank tracking functionality offers both standard and local rank monitoring across supported search engines and geographic locations spanning multiple countries.

Account tiers govern rate limiting and queue priority based on deposit volume with default tier accounts subject to limited concurrent requests, growth tier accounts eligible for unlimited concurrent requests with priority access, and scale tier accounts granted unlimited concurrent requests with highest priority.

New accounts receive free search requests upon registration without requiring credit card information. A pay as you go pricing structure applies volume based discounts through tiered deposit thresholds and separate pricing for web, news, image, and video search categories.
