Event metering you can trust at any scale
Stream billions of usage events with at-least-once guarantees, automatic deduplication, and real-time aggregation across any time window.
How Flexprice metering works
A metering pipeline that handles the hard parts: deduplication, ordering, and aggregation correctness — so your billing numbers match your system of record.
Event ingestion at scale
Ingest up to 100M+ events/month via REST API, SDKs, or Kafka. Built-in buffering and backpressure handling prevent data loss under traffic spikes.
Idempotency and deduplication
Every event carries an idempotency key. Duplicate submissions (retries, at-least-once delivery) are silently dropped — your usage totals stay accurate.
Flexible time windows
Aggregate by billing period, calendar month, rolling 30-day, or custom windows. Switch aggregation logic without migrating raw event data.
Real-time and batch modes
Query current-period usage in real-time via the API. Batch reconciliation catches any stragglers from delayed event delivery.
Exactly-once semantics
Atomic writes and idempotent counters guarantee that every event is counted once — no matter how many times your client retries.
