# Get storage volume over time

GET https://api.respan.ai/api/dashboard/storage-volume/

Returns storage volume metrics as a time series.

Reference: https://respan.ai/docs/apis/metrics/get-storage-volume-over-time

## 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

- `summary_type` (enum, optional, default: all) — Preset time range for the storage volume query.
  - Allowed values: `daily`, `weekly`, `monthly`, `quarterly`, `yearly`, `last_24h`, `all`
- `date` (date, optional) — Base date used with `summary_type` presets.
- `timezone_offset` (double, optional, default: 0) — Timezone offset, in hours, used when resolving preset ranges.

## Response

### 200

Successful response.

- `data` (list of DashboardStorageRow, required)

## Errors

### 403 Forbidden Error

The API key is missing, invalid or expired.

- `detail` (string, required)

## Types

### DashboardStorageRow

- `date_group` (datetime, optional)
- `total_bytes` (integer, optional, nullable)
- `object_count` (integer, optional, nullable)
- `standard_bytes` (integer, optional, nullable)
- `glacier_ir_bytes` (integer, optional, nullable)
- `deep_archive_bytes` (integer, optional, nullable)
