6         "content": "Aristotle (384–322 BC) was an Ancient\n                        Greek philosopher and polymath whose contributions\n                        have had a profound impact on various fields of\n                        knowledge.\n                        Here are some key points about his life and work:\n                        \n\n1. **Early Life**: Aristotle was born in 384 BC in\n                        Stagira, Chalcidice, which is near modern-day\n                        Thessaloniki, Greece. His father, Nicomachus, was the\n                        personal physician to King Amyntas of Macedon, which\n                        exposed Aristotle to medical and biological knowledge\n                        from a young age [C].\n\n2. **Education and Career**:\n                        After the death of his parents, Aristotle was sent to\n                        Athens to study at Plato's Academy, where he remained\n                        for about 20 years. After Plato's death, Aristotle\n                        left Athens and eventually became the tutor of\n                        Alexander the Great [C].\n                        \n\n3. **Philosophical Contributions**: Aristotle\n                        founded the Lyceum in Athens, where he established the\n                        Peripatetic school of philosophy. His works cover a\n                        wide range of subjects, including metaphysics, ethics,\n                        politics, logic, biology, and aesthetics. His writings\n                        laid the groundwork for many modern scientific and\n                        philosophical inquiries [A].\n\n4. **Legacy**:\n                        Aristotle's influence extends beyond philosophy to the\n                          natural sciences, linguistics, economics, and\n                          psychology. His method of systematic observation and\n                          analysis has been foundational to the development of\n                          modern science [A].\n\nAristotle's comprehensive\n                          approach to knowledge and his systematic methodology\n                          have earned him a lasting legacy as one of the\n                          greatest philosophers of all time.\n\nSources:\n                          \n- [A] Aristotle's broad range of writings and\n                          influence on modern science.\n- [C] Details about\n                          Aristotle's early life and education.",

Engage with an intelligent agent for information retrieval, analysis, and research.

This endpoint offers two operating modes:

RAG mode: Standard retrieval-augmented generation for answering questions based on knowledge base
Research mode: Advanced capabilities for deep analysis, reasoning, and computation

RAG Mode (Default)

The RAG mode provides fast, knowledge-based responses using:

Semantic and hybrid search capabilities
Document-level and chunk-level content retrieval
Optional web search integration
Source citation and evidence-based responses

Research Mode

The Research mode builds on RAG capabilities and adds:

A dedicated reasoning system for complex problem-solving
Critique capabilities to identify potential biases or logical fallacies
Python execution for computational analysis
Multi-step reasoning for deeper exploration of topics

Available Tools

RAG Tools:

search_file_knowledge: Semantic/hybrid search on your ingested documents
search_file_descriptions: Search over file-level metadata
content: Fetch entire documents or chunk structures
web_search: Query external search APIs for up-to-date information
web_scrape: Scrape and extract content from specific web pages

Research Tools:

rag: Leverage the underlying RAG agent for information retrieval
reasoning: Call a dedicated model for complex analytical thinking
critique: Analyze conversation history to identify flaws and biases
python_executor: Execute Python code for complex calculations and analysis

Streaming Output

When streaming is enabled, the agent produces different event types:

thinking: Shows the model’s step-by-step reasoning (when extended_thinking=true)
tool_call: Shows when the agent invokes a tool
tool_result: Shows the result of a tool call
citation: Indicates when a citation is added to the response
message: Streams partial tokens of the response
final_answer: Contains the complete generated answer and structured citations

Conversations

Maintain context across multiple turns by including conversation_id in each request. After your first call, store the returned conversation_id and include it in subsequent calls. If no conversation name has already been set for the conversation, the system will automatically assign one.

Request

This endpoint expects an object.
