Three lines to your first metered event.

Typed SDKs for Node, Python, and Go. Ingest usage from any inference call — the billing happens after, without your code knowing about it.

Metering API

Ingest usage events with cost attribution per model and customer.

Billing cycles

Compose seats, tiers, credits, and overage into one invoice.

Margin analytics

Revenue vs inference cost per customer, queryable.

Webhooks

Subscribe to invoice, payment, and spend-limit events.

  },
});
