Trusted in demanding API environments

Kumuluz API has been used by organizations across banking, insurance, aviation maintenance and enterprise services, including OTP banka, Generali, Prva zavarovalnica, Zavarovalniška skupina Sava, Adria Tehnika and others.

These organizations operate in environments where APIs must be secure, reliable, visible and governed — supporting internal integration, partner ecosystems, digital services, long-term API lifecycle management and increasingly also AI-enabled automation.

Secure, reliable, visible and governed APIs — for humans, applications, partners and AI agents.

APIs become difficult to manage when they grow without a platform

APIs are now the foundation of digital products, integrations, mobile applications, partner ecosystems, internal business platforms and AI-enabled automation.

But as the number of APIs grows, so does complexity. Organizations often lose visibility into which APIs exist, who uses them, how they are secured, which applications depend on them and how changes will affect consumers.

With AgenticAI, the challenge becomes even bigger. AI agents need controlled access to business APIs, tools, LLMs, context and workflows. Without a governed API layer, agents may connect directly to backend systems, use inconsistent tool definitions or operate without sufficient visibility, validation and auditability.

Kumuluz API provides the structure organizations need to manage APIs as reusable, secure and governed digital assets — for humans, applications, partners and AI agents.

Lack of API visibility

Teams do not always know which APIs already exist, what they do, who owns them or who is using them.

Duplicated business capabilities

Without a central API catalog, teams may rebuild the same functionality multiple times.

Uncontrolled access

API consumers, access plans, API keys, authentication and usage policies become difficult to manage consistently.

Risky API changes

Changing an API can break applications, integrations, partner systems or AI agent workflows if dependencies are not understood.

Ungoverned AI agent access

AI agents need APIs and tools, but exposing backend systems directly can create security, reliability and compliance risks.

Limited visibility into AI usage

Without API-level logging, LLM routing visibility and token usage tracking, organizations cannot properly monitor agent-driven consumption.

A central platform for API management, API economy and AgenticAI integration

Kumuluz API is an API management platform that helps organizations manage the full lifecycle of APIs — from cataloging and documentation to access control, onboarding, gateway management, monitoring, controlled change and AI-agent-ready exposure.

It provides a central view of APIs across the organization and helps teams expose business capabilities in a structured, secure and reusable way.

Kumuluz API supports internal API management, external API ecosystem scenarios, partner integrations, B2B APIs, API economy initiatives and AgenticAI architectures where APIs become governed tools for AI agents.
