# Open a CLI listen session

`GET https://api.morevoice.ai/v1/cli/listen`

The stream behind the CLI's `listen` command: your organisation's events for this key's mode (each with the exact body and Standard Webhooks headers to POST to your local endpoint, signed with the session's secret) and, with `forward_tools=true`, tool calls to answer from your machine — tools whose URL is `cli://<name>` and, in test mode, every webhook tool of your test calls. The session ends when the stream closes. Use a test key; a live key needs `live=true` and the `webhooks:write` scope. Counts against the key's stream limit.

Authenticate with a secret API key: `Authorization: Bearer $MOREVOICE_API_KEY`.

Operation ID: `cli_listen_stream`.

## Parameters

### Query parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `events` | `string \| string[]` | no | Event types to forward: a type (`call.ended`), a group (`call.*`) or `*`; comma-separated or repeated. Default: every event (opt-in live types only when named). |
| `forward_tools` | `"true" \| "false"` | no | `true`: this session answers tool calls — tools whose URL is `cli://<name>` and, in test mode, every webhook tool of the organisation's test calls. Needs the `tools:write` scope. |
| `live` | `"true" \| "false"` | no | Required (`true`) with a live key: live events and tool calls of live calls reach your machine. Needs the `webhooks:write` scope. |
| `last_event_id` | `string` | no | Resume after this event (`evt_…`), for clients that cannot send `Last-Event-ID`. |

### Headers

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `MoreVoice-Version` | `string` | no | The API version to use for this request. Defaults to the version the API key is pinned to. |

### 401 Unauthorized

### 403 Forbidden

Too many requests, or no call capacity right now. Retry after the Retry-After delay. Returns `ErrorEnvelope`.

### 500 Internal Server Error
