Enqueues traces, observations or sessions on a review
queue. Each item names exactly one object, either by traceId / observationId /
sessionId or by objectType plus objectId; every item enters PENDING. A queue
id belonging to another org is a 404.

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

## Examples

**CLI**

```bash
hanzo o11y reviews items create <id>
```

**SDK**

**.ts**

```ts
import { Configuration, O11yApi } from 'hanzoai';

const api = new O11yApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postO11yReviewsByIdItems({ id: 'id', id: "<id>", items: [{"assignee":"<assignee>","objectId":"<objectId>","objectType":"<objectType>","observationId":"<observationId>"}] });
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import O11yApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = O11yApi(client).post_o11y_reviews_by_id_items(id='id', id="<id>", items=[{"assignee":"<assignee>","objectId":"<objectId>","objectType":"<objectType>","observationId":"<observationId>"}])
```

**.go**

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

resp, _, err := client.O11yAPI.PostO11yReviewsByIdItems(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, o11y_api};

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

let result = o11y_api::post_o11y_reviews_by_id_items(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.O11yApi;

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

var result = new O11yApi(client).postO11yReviewsByIdItems();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/o11y/reviews/<id>/items \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "id": "<id>",
       "items": [
         {
           "assignee": "<assignee>",
           "objectId": "<objectId>",
           "objectType": "<objectType>",
           "observationId": "<observationId>"
         }
       ]
     }'
```

**MCP**

MCP reaches **o11y** through the `o11y` tool, which names its 307 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_o11y_autocomplete_aggregate_attributes"
         }
       }
     }'
```
