API
The AGENTIC STAR API provides two families depending on your use case: the Agent API and the LLM Gateway.
What is the AGENTIC STAR API?
The Agent API enables real-time conversations with autonomous AI agents. The SaaS edition supports three connection methods (SSE, MCP, and A2A) and also provides REST APIs for user management. The Marketplace edition connects via Chat API / SSE. Conversation history and file management REST APIs are available in both editions.
The LLM Gateway is a raw LLM call (a governance proxy) compatible with OpenAI / Anthropic. You can use it by simply swapping the base URL of your existing OpenAI SDK / Anthropic SDK (SaaS only).
The Two API Families
| Family | Use Case | Representative Endpoint |
|---|---|---|
| Agent API | Running autonomous agents (including tool execution and deliverable generation) | /api/v1/chat/completions |
| LLM Gateway | Direct OpenAI / Anthropic-compatible LLM calls | /llm/v1/chat/completions |
If you need agent features such as tool execution, deliverables, or conversation history, choose the Agent API. If you just want to call a raw LLM in an OpenAI / Anthropic-compatible way, choose the LLM Gateway.

LLM Gateway
OpenAI / Anthropic-compatible LLM calls (SaaS only). Use it by swapping the base URL of your SDK.
