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.
OneRouter provides a unified, standardized API layer that integrates multiple industry-leading AI search models and agents into a single, seamless interface. This allows developers and enterprises to access diverse search and reasoning capabilities without managing complex, model-specific integrations.
Currently, OneRouter has integrated the following major AI search models & agents:
🔹 Tavily
Tavily combines LLM-based comprehension with structured web search, providing accurate, source-backed results optimized for retrieval-augmented generation workflows. It excels at grounding AI responses in verifiable content.
🔹 Exa
Exa offers developer-friendly APIs for semantic web search, enabling fast, high-quality search experiences across diverse data domains. It focuses on efficient embedding-based retrieval and ranking.
🔹 Jina
Jina is a versatile multimodal search framework. Through its AI-powered query understanding and neural retrieval capabilities, Jina enables flexible search experiences that go beyond pure text — including image, audio, and hybrid search.
🔹 Firecrawl
Firecrawl introduces an agent-based crawling approach to expand search coverage dynamically. It continuously learns from user queries and web structures to deliver updated summaries and insights from the open web.
🔹 Perplexity
Perplexity AI represents the next generation of conversational search agents. It combines web retrieval with LLM reasoning to provide human-like, cited answers that merge search and dialogue seamlessly.
Unified Integration: Access multiple AI search providers through one consistent interface.
Dynamic Routing: Automatically route queries to the best-performing search model based on task type.
Scalability & Reliability: Built-in monitoring, caching, and fallback mechanisms ensure stable performance.
Continual Expansion: Constant integration of new AI search agents and APIs as the search ecosystem evolves.
