# List span groups

GET https://api.respan.ai/api/request-logs/groups/

Group spans by a supported dimension and return one aggregate row per group. `trace` and `thread` roll spans up through their dedicated entity views.

Reference: https://respan.ai/docs/apis/spans/list-span-groups

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.
- `Authorization` header (bearer token, required) — Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead.

## Request

### Query parameters

- `group_by` (enum, optional, default: model) — Grouping dimension. `trace` and `thread` use entity rollups.
  - Allowed values: `model`, `provider_id`, `organization_key_id`, `prompt_id`, `deployment_id`, `deployment_name`, `custom_identifier`, `customer_identifier`, `trace`, `thread`
- `sort_by` (string, optional, default: number_of_requests)
- `start_time` (datetime, optional)
- `end_time` (datetime, optional)
- `environment` (string, optional)
- `page` (integer, optional)
- `page_size` (integer, optional)

## Response

### 200

Paginated groups and aggregate metrics.

- `count` (integer, required) — Number of results on this page, not the total. Request pages until `next` is null to get every result.
- `results` (list of ApiRequestLogsGroupsGetResponsesContentApplicationJsonSchemaResultsItems, required)
- `next` (string, optional, nullable)
- `previous` (string, optional, nullable)
- `current_filters` (map from string to any, optional)
- `filters_data` (map from string to any, optional)

## Errors

### 400 Bad Request Error

Unsupported group_by value. Invalid sort_by falls back to number_of_requests.

- `error` (string, required)

### 403 Forbidden Error

The API key is missing, invalid or expired, or it doesn't grant analytics read access.

- `detail` (string, required)

## Types

### ApiRequestLogsGroupsGetResponsesContentApplicationJsonSchemaResultsItems

Aggregated metrics plus the selected group key. Trace and thread groups include their richer entity fields.

- `date_group` (datetime, optional)
- `model` (string, optional)
- `provider_id` (string, optional)
- `organization_key_id` (string, optional)
- `prompt_id` (string, optional)
- `deployment_id` (string, optional)
- `deployment_name` (string, optional)
- `custom_identifier` (string, optional)
- `customer_identifier` (string, optional)
- `trace_unique_id` (string, optional)
- `thread_identifier` (string, optional)
- `number_of_requests` (integer, optional, nullable)
- `span_count` (integer, optional, nullable)
- `total_cost` (double, optional, nullable)
- `total_tokens` (integer, optional, nullable)
- `error_count` (integer, optional, nullable)
- `error_percentage` (double, optional, nullable)
- `average_cost` (double, optional, nullable)
- `average_tokens` (integer, optional, nullable)
- `average_latency` (double, optional, nullable)
- `average_ttft` (double, optional, nullable)
- `average_tps` (double, optional, nullable)
- `cache_hit_percentage` (double, optional, nullable)
