| **Address**   | `https://api.hanzo.ai/v1/benchmark/catalog` |
| **Method**    | `GET`                                       |
| **Operation** | `get_benchmark_catalog`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`      |

The canonical public benchmarks this arena runs — the id, title, axis,
item count and upstream source of each, with native marking the ones the
standardized harness runs today; the rest are registered and adapter-pending.

These ids are the vocabulary the rest of the surface takes: a run names them, and
the leaderboard and compare read them from ?benchmark=. The catalog is
deployment-wide and identical for every caller — there is no tenant in it.

## Request

`GET /v1/benchmark/catalog` takes no parameters and no body — the credential is the whole request.

## Response

| Status    | Body                       | Meaning |
| --------- | -------------------------- | ------- |
| `200`     | benchmark.benchmarkCatalog | ok      |
| `default` | problem-details            | refused |

`200` body — 8 fields.

| Field           | In   | Type                   | Always | Description                                                |
| --------------- | ---- | ---------------------- | ------ | ---------------------------------------------------------- |
| `data`          | body | benchmark.Benchmark\[] | —      | Data is one row per benchmark, in the catalog's own order. |
| `data[].axis`   | body | string                 | —      | what capability it measures                                |
| `data[].id`     | body | string                 | —      | the id every other op on this surface takes                |
| `data[].items`  | body | integer (int64)        | —      | how many items it holds, when the set is fixed             |
| `data[].native` | body | boolean                | —      | whether the standardized harness runs it today             |
| `data[].source` | body | string                 | —      | where the items come from                                  |
| `data[].title`  | body | string                 | —      | the benchmark's published name                             |
| `total`         | body | integer (int64)        | —      | Total is how many rows Data holds.                         |

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

## Examples

**CLI**

```bash
hanzo benchmark catalog
```

**SDK**

**.ts**

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

const api = new BenchmarkApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getBenchmarkCatalog();
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = BenchmarkApi(client).get_benchmark_catalog()
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new BenchmarkApi(client).getBenchmarkCatalog();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/benchmark/catalog \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

Tool `benchmark`, op `get_benchmark_catalog` — POST the JSON-RPC envelope to `https://api.hanzo.ai/v1/mcp`.
