# API monetization ready for the Agentic Era
Meter, bill, and monetize APIs as products ready for human *and* non-human customers.
## Turn existing APIs and event streams into new revenue streams
Build API and event data product entitlements, meter usage in real-time, and bill customers based on consumption.
Eliminate the need to build and maintain custom monetization functionality, and ship monetized functionality faster.
Monetization isn’t just about direct revenue generation. It's also about governing the internal resource usage that drives AI systems. Do both in Konnect.
## Revolutionize how you integrate
## Publish APIs as self-service API products
Monetized products need a digital catalog for customer visibility. Build your catalog with the Konnect Developer Portal so that APIs become self-serve, easily discoverable, monetized API products – complete with API documentation and self-serve registration.
## Design and enforce API product subscription tiers
Design product tiers and subscription mechanisms that define API resource entitlements as subscription tiers. Enforce those entitlements via rate limiting in Kong runtime infrastructure.
## Metering and billing
Monitor and meter against API resource consumption in real-time. Integrate with payment gateways and ERPs to bill and collect revenue.
## Monetize event data products, too
REST APIs aren’t the only data sources that Agents and AI applications will leverage – event data will be crucial. Monetize access to the data that agents will rely upon for real-time decision making.
## Internal cost governance
Agents and AI systems are expensive, and most organizations still [struggle to control costs](https://konghq.com/blog/enterprise/hidden-ai-connectivity-tax)struggle to control costs. Take the metering, billing, and entitlement enforcements you use for direct monetization, and reuse them for internal cost governance and internal cost-sharing mechanisms.
