# Get span summary

`POST /api/request-logs/summary/`

## Request

- Base URL: `https://api.respan.ai`
- URL: `https://api.respan.ai/api/request-logs/summary/`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Returns aggregate span statistics for a time range. Send `start_time`, `end_time`, and `environment` as query parameters, and additional `filters` in the JSON body. Fields such as `log_type` are not read from query parameters. Empty or omitted `filters` may use pre-aggregated data; non-empty `filters` query individual spans using the List spans filter format.

## Query parameters

- `start_time` string, date-time
- `end_time` string, date-time
- `environment` 'prod' | 'test'

## Request body

- object
  - `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.
