Reads a session's log in order, a page at a time: everything after the seq a
reader last saw, so a poll resumes exactly where it stopped. It is how to see
what a run did and why it ended — each model turn, tool call, status and log
line, as the run wrote them. A run whose process went away is ended first,
with its reason as the last event.

## Request

3 fields.

| Field   | In    | Type    | Required | Description                                                                |

| `after` | query | integer | —        | After is the seq of the last event already read; the page starts after it. |
| `limit` | query | integer | —        | Limit caps the page.                                                       |

| Field                | In   | Type               | Always | Description                                                                                                                                                                                  |
| -------------------- | ---- | ------------------ | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `events`             | body | agent.eventView\[] | —      | Events is the page, in seq order.                                                                                                                                                            |
| `events[].actor`     | body | string             | —      | Actor is who produced the turn.                                                                                                                                                              |
| `events[].createdAt` | body | string             | —      | CreatedAt is when the turn was recorded, RFC 3339 in UTC to the second.                                                                                                                      |
| `events[].id`        | body | string             | —      | ID is the event's own handle, minted as "evt\_" + 32 hex characters.                                                                                                                         |
| `events[].kind`      | body | string             | —      | Kind is what the turn IS, from a closed six: message (a model turn), tool-call, spawn (a subagent started), log, status, control (a steering command the running surface consumes).          |
| `events[].payload`   | body | any                | —      | Payload is the turn's body, embedded as JSON rather than as a string — whatever the writer sent, up to 64 KiB, checked for well-formedness and scanned for credentials before it was stored. |
| `events[].seq`       | body | integer (int64)    | —      | Seq is the turn's position in this session's log: monotonic from 1, assigned by the store inside the insert, and unique PER SESSION rather than globally.                                    |
| `events[].sessionId` | body | string             | —      | SessionID is the session this turn belongs to.                                                                                                                                               |
| `next`               | body | integer (int64)    | —      | Next is the seq to pass as after for the page beyond this one; absent when this page reached the end of the log as it stands now.                                                            |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo agent sessions events get <id>
```

**SDK**

**.ts**

```ts
import { Configuration, AgentApi } from 'hanzoai';

const api = new AgentApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getAgentSessionsByIdEvents({ id: 'id' });
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import AgentApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = AgentApi(client).get_agent_sessions_by_id_events(id='id')
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.AgentAPI.GetAgentSessionsByIdEvents(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, agent_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = agent_api::get_agent_sessions_by_id_events(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.AgentApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new AgentApi(client).getAgentSessionsByIdEvents();
```

The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree. [SDKs →](https://docs.hanzo.ai/docs/sdks)

**HTTP**

```bash
curl https://api.hanzo.ai/v1/agent/sessions/<id>/events \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **agent** through the `agent` tool, which names its 51 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_agents"
         }
       }
     }'
```
