We read token counts, metadata, and cost endpoints. We never store raw prompts or customer data.
Common questions, direct answers.
What exactly counts as a "Log Event"?
A log event is a single tracked AI call you send us through the SDK or API: one chat completion, one embedding request, one tool call. We read token counts, model, cost, and the metadata you attach. Your monthly limit counts these events, not tokens, and we never store raw prompts or completions.
What happens if I go over my monthly event limit?
On Growth and Scale, extra events are billed as overage ($0.15 per 1,000 on Growth, $0.10 per 1,000 on Scale), so nothing stops working. The Developer free tier caps at 10,000 events per month; when you reach it we prompt you to upgrade rather than bill you.
How long does it take to integrate Bear Lumen into my app?
Most teams are sending live data within a few minutes. Drop in the Node.js or Python SDK, or wire up the MCP and Skill files, and your cost and margin dashboard starts filling in immediately. No data warehouse or pipeline work required.
Do you offer custom pricing if we bring our own self-hosted models?
Yes. Enterprise plans support self-hosted and custom models, dedicated ingestion queues, a data processing agreement (DPA), multi-year retention, and a custom SLA. Talk to the founder and we will shape a plan around your stack.
