# Get Agent Session Voice Capability

`GET /agent/sessions/{session_id}/voice`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/agent/sessions/{session_id}/voice`
- Auth: HTTP bearer

Can voice be used on THIS session.

Differs from the workspace answer by also checking the caller owns the
session, so it is the one to ask before showing a microphone on a specific
conversation.

## Path parameters

- `session_id` string, required: Session id (UUID).

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Response `200`

Successful Response

- ApiResponseAgentSessionStatePayload
  - `data` AgentSessionStatePayload, required: An open envelope for a hydration or voice answer. Open because session hydration returns the agent's STEPS as well as its messages, and a step's `detail` is whatever the tool that produced it reported. That set grows with every tool the platform gains, and a pinned mirror would drop the detail of exactly the newest ones - which on a transcript surface reads as the agent having done less than it did.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
