Magnus API
Magnus API · in your own system

AI that actually executes. Without losing control.

The same Magnus agents, inside your own app: an OpenAI-compatible API and SDKs, with rules that decide, confirmation before anything irreversible and a trace of every turn.

You stay in control — define what can and can’t happen
Human in the loop — approve critical actions
Fully auditable — every decision, every step

The Shift to Execution

Magnus replaces fragmented AI calls with a unified agent execution runtime.

Legacy Web Apps

  • Isolated prompt-response calls
  • Fragile custom glue logic
  • Deterministic paths require hardcoding
  • No state awareness between interactions
  • Black-box decision making

Agent Execution Runtime

  • Active decision-driven agents
  • Engine decides the optimal next step
  • Native execution of system actions
  • Persistent state and execution context
  • Fully auditable reasoning traces
"Magnus doesn't respond to prompts. Magnus executes processes."
Execution Transformation

Unlock decision-driven
agents in 3 steps

Move beyond simple responses to agents that execute real actions and manage state — without changing your stack.

01

1. Run

Point your OpenAI client at Magnus: a new base URL and your Magnus key.

02

2. Decide

Set the behavioral constraints and decision-making logic for your agent.

03

3. Act

Run agents that execute real actions across your systems.

What Magnus API is

Infrastructure to operate AI, not another LLM wrapper.

What it IS

  • A decision engine at its core
  • A centralized LLM Gateway
  • A policy and security engine
  • A memory and context layer (RAG)

What it is NOT

  • A generic 'no-code' chatbot
  • A simple OpenAI wrapper
  • An isolated vector database
  • A UI design tool

Runtime Capabilities

Native agent execution. Everything you need to scale agent-driven operations.

True Multi-tenancy

Data, keys and agents isolated per organization.

Execution Gateway

Automatic failover between OpenAI and Google Gemini. On paid plans, bring your own provider key.

Decision Engine

Deterministic engine that operates within defined rules and coordinates cross-system actions.

Knowledge & Context

Shared knowledge injection from your private systems. Exact citations and state-aware retrieval.

Persistent State

Conversation state kept on the server: each end user's conversation continues where it left off.

System Actions

Ready connectors for Jira and SAP (read-only), plus your own APIs and MCP servers.

Outcome Engine

Transforms agent reasoning into structured execution over real systems.

Human Loop

Smart handoff to human operators when the agent detects ambiguity — maintaining full state context.

Full Observability

Per-turn traces and token usage. Every agent decision is auditable.

Built for real-world execution

Security and trust at every layer of the product.

No black boxes

No hidden decisions, everything is transparent.

Full traceability

All actions are auditable in real-time.

Role-based permissions

Granular control over who can do what.

Controlled autonomy

AI operating on your terms, always.

One agent, two ways to use it

Don't want to write code?

It is the same agent, with the same rules. All you choose is where it serves.

In your system

Magnus API

Your own app, website or CRM talks to the agent through an OpenAI-compatible API and SDKs. The interface and the brand stay yours.

You are here

In your channels

Magnus Agents

The same agent serves on WhatsApp, Telegram and your website chat, set up from the dashboard. No code.

Frequently Asked Questions

LLMs are probabilistic and change over time. Magnus transforms them into deterministic tools. We wrap the model's intelligence with a 'Decision Engine' that ensures business rules are always met, regardless of the LLM's variability.

LangChain is great for low-level prototyping. Magnus is an agent execution runtime designed for enterprise production. We prioritize predictability and deterministic decisions over experimental autonomy.

Agents can interact with Jira, schedule appointments, manage tickets, and call any REST API. They also connect to external MCP (Model Context Protocol) servers.
