Returns the consumer topic-throughput overview for the

## Request

5 fields, body `application/json` (required).

| Field         | In   | Type            | Required | Description                                                                                                                 |
| ------------- | ---- | --------------- | -------- | --------------------------------------------------------------------------------------------------------------------------- |
| `end`         | body | integer (int64) | —        | End is the window's end, epoch nanoseconds.                                                                                 |
| `eval_time`   | body | integer (int64) | —        | EvalTime bounds the span-evaluation scan, nanoseconds; only the span/evaluation view reads it.                              |
| `start`       | body | integer (int64) | —        | Start is the window's start, epoch nanoseconds.                                                                             |
| `variables`   | body | object          | —        | Variables name what the view drills into — topic, partition, service, consumer\_group — keyed by the name the view expects. |
| `variables.*` | body | string          | —        |                                                                                                                             |

## Response

| Status    | Body                   | Meaning           |
| --------- | ---------------------- | ----------------- |
| `200`     | o11y.O11yQueryRangeOut | ok                |
| `202`     | Approval               | held for approval |
| `default` | problem-details        | refused           |

`200` body — 2 fields.

| Field    | In   | Type   | Always | Description                                                                                                              |
| -------- | ---- | ------ | ------ | ------------------------------------------------------------------------------------------------------------------------ |
| `data`   | body | any    | —      | Data is the query result — the result type, the result set, execution stats and any warning — as the engine rendered it. |
| `status` | body | string | —      | Status is "success".                                                                                                     |

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

## Examples

**CLI**

```bash
hanzo o11y messaging-queues kafka topic-throughput consumer
```

**SDK**

**.ts**

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

const api = new O11yApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postO11yMessaging-queuesKafkaTopic-throughputConsumer({ end: 0, eval_time: 0 });
```

**.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_messaging-queues_kafka_topic-throughput_consumer(end=0, eval_time=0)
```

**.go**

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

resp, _, err := client.O11yAPI.PostO11yMessaging-queuesKafkaTopic-throughputConsumer(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_messaging-queues_kafka_topic-throughput_consumer(&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).postO11yMessaging-queuesKafkaTopic-throughputConsumer();
```

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.

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/o11y/messaging-queues/kafka/topic-throughput/consumer \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "end": 0,
       "eval_time": 0
     }'
```

**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"
         }
       }
     }'
```
