# Get Vapi Latency Stats

`GET /developer/vapi-latency/stats`

Aggregated latency stats for the dashboard, broken out by individual
model per pipeline component (LLM / voice / transcriber). All aggregation
runs in SQL so it scales on prod. Time filter applies to
``VapiCallLatency.ended_at``.

## Query parameters

- `time_range` '24h' | '7d' | '30d' | 'all'

## Response `200`
