# List Agent Trace Summary Versions

GET https://api.getzep.com/api/v4/agents/{agent_uuid}/traces/{trace_uuid}/summary/versions

Reference: https://help.getzep.com/sdk-reference/agent/traces/list-summary-versions

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key  `) — Type "Api-Key" followed by a space and the project API key.

## Request

### Path parameters

- `agent_uuid` (string, required) — Agent UUID
- `trace_uuid` (string, required) — Trace UUID

### Query parameters

- `page_size` (integer, optional, default: 50) — The maximum number of items in one page. The SDK method returns a pager. In Python, `.items` holds only the first page. In TypeScript, `.data` holds only the first page. To read every page, iterate the pager: use `for` or `list(...)` in Python, or `for await` in TypeScript. In Go, the method returns one page, and `Iterator()` reads all pages.
- `cursor` (string, optional) — Opaque page cursor
