# Get LLM metrics over time

`POST /api/dashboard/llm-metrics/`

## Request

- Base URL: `https://api.respan.ai`
- URL: `https://api.respan.ai/api/dashboard/llm-metrics/`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Returns LLM usage metrics in time buckets set by `time_tick`.

## Query parameters

- `summary_type` 'daily' | 'weekly' | 'monthly' | 'quarterly' | 'yearly' | 'last_24h' | 'all'
- `date` string, date
- `start_time` string, date-time
- `end_time` string, date-time
- `time_tick` 'minute' | 'hour' | 'day'
- `timezone_offset` number
- `fetch_filters` 'true' | 'false'

## Request body

- DashboardFiltersRequest: Optional POST body. Only `filters` is read from the body; time range controls are URL query parameters.
  - `filters` Filters: Each key is a field to filter on, and each value is a condition: `{"<field>": {"operator": "<operator>", "value": [...]}}`. A result must match every condition. To set two conditions on one field, such as a range, pass a list of conditions. **Operators:** `""` (equals, the default), `not`, `in`, `not_in`, `lt`, `lte`, `gt`, `gte`, `contains`, `not_contains`, `icontains` (ignores case), `startswith`, `not_startswith`, `endswith`, `not_endswith`, `empty`, `not_empty`. Put values in a list: `""` and `in` match any of the listed values, and `not` and `not_in` match none of them. Other operators take one value; for `empty` and `not_empty`, send `[""]`. The fields you can filter on depend on the endpoint; `metadata__<key>` filters custom metadata where the endpoint supports it.
    - `status` FilterValue: A filter condition with an operator and value.
