`GET /v1/projects/{projectSlug}/sessions/{sessionId}/memory`

## Path parameters

- `projectSlug` string, required — Project slug (human-readable identifier)
- `sessionId` string, required — Session identifier lifted from instrumentation. Up to 128 characters.

## Query parameters

- `traceId` string — Restrict the memory footprint to this trace of the session. Omit for the whole session.

## Response `200`
