The SERP section helps you quickly choose the right search engine and understand which filters, localization options, and pagination controls are available for each engine.

• If you want to pick an engine first, start with Supported Engines
• If you want to understand the recurring filters first, start with Common Parameters
• If you already know the engine you want, jump straight to its page in the sidebar

This section complements the Search API Reference:

• The API reference focuses on the public request / response contract
• The SERP section focuses on what you can search, what you can control, and where to find the right engine-specific details

What You Can Do Here

• Compare the supported engines and decide whether you need Google, Bing, DuckDuckGo, or a more specialized source
• Learn which parameters are shared across engines and which ones are engine-specific
• Check the required fields, filters, pagination controls, and localization options for a single engine

How To Read This Section

• If this is your first time with SERP, go in the order: overview -> supported engines -> common parameters -> engine page
• If you already know the engine, go straight to the engine page and use the parameter groups there
• Field descriptions are preserved from the live backend metadata so the docs stay close to what the engine actually supports

Usage Notes

• Requiredness should be read from the field-level must flag
• Parameters with the same name are not always interchangeable across engines
• For very large enum lists, this section shows the shape and examples while the live metadata remains the source of truth
