Usage-Based Billing for AI Agents with FastAPI and Kong
This is where billing starts. Every time a user makes an API call, you'll send a usage event to Konnect Metering & Billing. The metering layer (powered by the open-source OpenMeter engine) ingests and aggregates these events. You'll talk to the API directly using standard HTTP calls, no extra dependencies needed.

ClickHouse for usage metering with Kafka Connect
This plugin guarantees exactly-once delivery between Kafka topics and ClickHouse tables, which is critical, as Kafka Connect tasks are only aware of the latest topic offset acknowledged by the consumer. For example, consumers can fail to acknowledge a processed offset due to a network error or an exception. This is great as exactly-once inserts prevent dropping or double-inserting usage, leading to incorrect billing.
In OpenMeter, we pre-aggregate usage events into one-minute tumbling windows to reduce the number of rows we need to scan at query time. To do this, with ClickHouse, we use the AggregatingMergeTree table engine that enables incremental data aggregation when combined with MaterializedView. In ClickHouse, MaterializedViews are trigger-based and update when new records are inserted into the source table. Consequently, the corresponding materialized views are updated whenever Kafka Connect transfers a batch of events to ClickHouse. This also means inserts can fail when the view cannot process a record at trigger. We send failed events into the Dead Letter Queue topic for later processing.
To help ClickHouse with hot topics, we will consider adding an extra streaming aggregation step for high-producers, but this time with a more horizontally scalable stream processor like Arroyo. This would reduce ClickHouse insert batch sizes. Based on our tests, ClickHouse works best if batch sizes are 50-100k and less frequent than per second.
