# Stream a call's live events

`GET https://api.morevoice.ai/v1/calls/{id}/events`

Server-Sent Events for one call: `call.state_changed`, `transcript.partial`, `transcript.final`, `call.tool_called`, and `call.ended`, after which the stream closes. The stream starts with what already happened on the call. Reconnect with `Last-Event-ID` (EventSource does it for you) to get only what you missed. An ended call's stream sends `call.ended` at once. A call that has not started yet (a web call before the browser connects) is a 404: subscribe once it starts, or follow it on GET /v1/events/stream. Counts against the key's stream limit (`concurrency_limit`, `limit_type: api_streams`).

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

Operation ID: `calls_stream`.

## Parameters

### Path parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | `string` | yes | A call ID (`call_…`). |

### Query parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `types` | `string \| string[]` | no | Only these event types (comma-separated or repeated): `call.state_changed`, `transcript.partial`, `transcript.final`, `call.tool_called`, `call.ended`, `transcript.*`, `call.*` or `*`. Default: all of them. |
| `last_event_id` | `string` | no | Resume after this event, for clients that cannot send the `Last-Event-ID` header (the header wins when both are sent). |

### 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. |

## Responses

### 200 OK

### 401 Unauthorized

No valid API key was sent. Returns `ErrorEnvelope`.

### 403 Forbidden

The key may not do this (a missing scope, a plan limit, or a compliance block). Returns `ErrorEnvelope`.

### 404 Not Found

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

Something went wrong on MoreVoice's side. Retry with the same Idempotency-Key. Returns `ErrorEnvelope`.
