General
What is Amlexia?
Operational intelligence for backends — see What is Amlexia?.

Billing & limits
Is there a free tier?
Yes — Startup plan: 10,000 events/month, 1 project, 7-day raw retention. See Plans & limits and pricing.
What happens if I exceed the monthly limit?
Ingest may return 402 (plan exceeded). SDKs surface this; upgrade or wait for the next billing month.
What happens on rate limit?
429 — SDKs retry with backoff.
Cost & LLM metrics
Does Amlexia compute LLM cost automatically?
Ingest enriches events with estimated cost_usd when you send model_name, provider, and token counts without a positive cost_usd. You can always send explicit cost_usd (reported). Dashboard shows reported vs estimated.
Do I still need to send cost for Stripe?
Yes for payment charts — send cost_usd from your charge/fee logic and provider: 'stripe'.
Dashboard
How do I filter staging vs production?
Set AMLEXIA_ENVIRONMENT in the SDK and use the dashboard environment filter. Use Compare for side-by-side env metrics.
What are saved views?
Named presets for time range, environment, and compare mode — saved per user per project.
Data
How long is data retained?
Per project Settings and plan — see Plans & limits.
GDPR?
DELETE /api/gdpr/sessions/:sessionId — see Dashboard API.
Integration
Serverless?
Call flush() or ctx.waitUntil(client.flush()) on Workers before the runtime freezes.
OpenTelemetry?

Frontend errors?
