# Search Engine API

## 🌐 What Is a Web Search Model & Agent?

A **Web Search Model** is an advanced AI system designed to understand user queries and retrieve the most relevant, accurate, and context-aware results from the web. Unlike traditional keyword-based search engines, modern web search models leverage large language models (LLMs) and retrieval-augmented generation (RAG) to interpret intent, reason over information, and deliver synthesized insights rather than just links.

A **Search Agent** extends this capability further — it is an autonomous or semi-autonomous agent powered by AI that can:

* Interpret natural language questions with context.
* Dynamically query search APIs, websites, or knowledge bases.
* Aggregate, filter, and summarize information.
* Present concise, actionable answers to the user.

Together, **web search models and agents** form the foundation for intelligent information retrieval in the AI era — enabling real‑time knowledge discovery, research automation, and data-informed decision-making.
