Lack of API visibility
Teams do not know which APIs already exist, who owns them or who is using them.
API Management & API Economy
Turn APIs into governed digital assets for teams, partners and AI agents
APIs are the foundation of digital platforms, partner ecosystems, business integrations and AI-enabled automation.
Kumuluz helps organizations expose, manage, secure and monitor APIs across teams, partners, digital channels and AgenticAI environments.
With Kumuluz API, you can build API catalogs, developer portals, gateway policies, access plans, sandboxes, API lifecycle processes and API economy foundations — while preparing APIs for AI agents, MCP-enabled integrations, contextual routing and AI usage visibility.

APIs create value only when they are visible, secure and reusable
Most organizations already have many APIs. Some support internal applications. Some connect partners. Some power mobile apps, portals or integration layers. Others expose business capabilities hidden in legacy systems.
But without a central API management approach, APIs become difficult to discover, secure, reuse and evolve.
Teams may duplicate functionality. Partners may require manual onboarding. API changes may break applications. Access policies may be inconsistent. API usage may not be visible.
With AI agents, the challenge becomes even more important. Agents need APIs as tools, but giving agents uncontrolled access to backend systems increases security, reliability and compliance risk.
API management is now not only about developers and partners — it is also about preparing APIs for safe use by AI agents.
Duplicated integrations
The same business capabilities are repeatedly rebuilt or exposed through inconsistent endpoints.
Manual partner onboarding
External developers and partners need documentation, access, sandbox environments and support.
Risky API changes
API changes can break applications, integrations, partner systems or agent workflows.
Uncontrolled agent access
AI agents need APIs, but direct backend access can bypass policies, validation and monitoring.
Limited API business value
APIs cannot become digital products unless they are discoverable, documented, secure and measurable.
A governed API ecosystem for digital and AgenticAI platforms
Kumuluz provides an API management and API economy solution that helps organizations manage APIs as reusable, governed and business-ready digital assets.
At the core is Kumuluz API, which provides API cataloging, documentation, developer onboarding, gateway management, access control, monitoring, change management, sandbox support and API economy capabilities.
The solution also supports modern AgenticAI scenarios. APIs can be prepared for AI-agent use, exposed through MCP-oriented patterns, routed through gateway policies and monitored for agent-driven usage, including LLM routing and token logging where needed.
Create API visibility
Build a central view of APIs, ownership, documentation, consumers, usage and dependencies.
Secure and govern access
Control who can use which APIs, under which plans, keys, policies and service-level conditions.
Enable partner ecosystems
Provide documentation, subscriptions, sandbox access and onboarding workflows for partners and developers.
Prepare APIs for AI agents
Expose APIs as governed tools for AI agents through MCP-oriented patterns, contextual routing and gateway-level checks.

From technical endpoints to API products
APIs create business value when they are treated as reusable digital assets.
An API economy approach helps organizations expose selected business capabilities to partners, internal teams, external developers and digital ecosystems in a structured way.
Kumuluz API supports this by providing cataloging, documentation, access plans, subscriptions, sandbox environments, monitoring and lifecycle control.
Productize APIs
Package APIs as reusable capabilities with documentation, ownership, access plans and lifecycle status.
Enable partner access
Give partners a controlled way to discover, test and consume APIs.
Create new channels
Use APIs to support digital partnerships, portals, mobile apps, platforms and B2B ecosystems.
Measure adoption
Track API usage, consumers, traffic and integration trends.
Manage change
Communicate updates, version changes and deprecations to API consumers.
Support business models
Use access plans, usage visibility and partner tiers as a foundation for API-based business models.
Prepare APIs for AI agents and AgenticAI platforms
AI agents need APIs to retrieve data, trigger actions, start workflows and interact with business systems.
But APIs designed only for traditional applications are not always safe or suitable for agentic use. Agents need controlled tool interfaces, clear schemas, permissions, validation, monitoring and execution boundaries.
Kumuluz helps organizations prepare APIs for AI-agent use. Kumuluz API can expose selected APIs through MCP-oriented patterns, route agent requests through gateway policies, perform basic checks, monitor usage and support LLM routing and token logging where needed. This enables APIs to become governed tools in an AgenticAI architecture.
Agent-callable APIs
Expose selected APIs as tools that AI agents can use under defined policies.
AgentsPolicies
MCP server patterns
Use MCP-oriented integration patterns so agents can discover and invoke approved capabilities.
MCPDiscovery
Kumuluz API MCP server
Kumuluz API can expose its own MCP server so agentic systems can integrate with the API management platform itself.
MCPIntegration
Contextual routing
Route agent requests based on context, policies, target capability, user role or execution requirements.
RoutingContext
Basic gateway checks
Validate request structure, access conditions and allowed execution patterns before backend invocation.
GatewayValidation
LLM routing
Route selected requests toward LLM services or AI processing layers where needed.
LLMRouting
Token usage logging
Record token usage and AI consumption information to support cost visibility and governance.
TokensGovernance
Agent dependency tracking

Governance and security across API consumers
API governance must cover all types of consumers: internal applications, partners, external developers, workflow engines and AI agents.
Kumuluz API helps organizations define consistent rules for who can access which APIs, how requests are routed, what policies apply and how usage is monitored.
API ownership
Define who owns, maintains and approves API changes.
Access policies
Control access through plans, subscriptions, API keys, authentication and authorization.
Consumer management
Track applications, partners, developers, systems and agents that use APIs.
Gateway enforcement
Apply routing, rate limits, quotas, policies and request checks at the gateway layer.
Version governance
Manage API versions, compatibility, deprecations and migrations.
Auditability
Track API calls, access events, agent requests, LLM routing and token usage where relevant.
Manage reusable business capabilities and workflows
API management becomes more valuable when APIs expose reusable business capabilities, not only technical endpoints.
Kumuluz Business APIs provide reusable business functions such as customer data, product catalogs, orders, payments, subscriptions, invoicing, KYC, onboarding, cases, tasks and notifications.
Kumuluz API can catalog, secure, expose and monitor those APIs for applications, partners, AI agents and workflow engines. In AgenticAI scenarios, Business APIs can become governed tools that agents use, while Temporal, Camunda or similar workflow engines execute process-critical steps deterministically.
Business capability catalog
