# List spans

`POST /api/request-logs/list/`

## Request

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

Filter on span fields with `filters`, and sort by evaluator scores. Metadata keys beginning with `_` are reserved for platform use and omitted from span and trace read responses.

## Query parameters

- `page` integer
- `page_size` integer
- `sort_by` string
- `start_time` string, date-time
- `end_time` string, date-time
- `environment` 'prod' | 'test'
- `log_type` 'text' | 'chat' | 'completion' | 'response' | 'embedding' | 'transcription' | 'speech' | 'workflow' | 'task' | 'tool' | 'agent' | 'handoff' | 'guardrail' | 'function' | 'custom' | 'generation' | 'unknown' | 'score' | 'batch' | 'span'
- `include_fields` string

## 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.
