| **Address**   | `https://api.hanzo.ai/v1/reference/{set}` |
| **Method**    | `DELETE`                                  |
| **Operation** | `riskClearReference`                      |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`    |

Removes one of your organisation's overrides.

It removes an entry your organisation wrote, never a baseline member: the
published set is not writable from here, so a removal can only ever restore
the baseline's own answer.

## Request

2 fields.

| Field | In    | Type   | Required | Description |
| ----- | ----- | ------ | -------- | ----------- |
| `set` | path  | string | yes      |             |
| `key` | query | string | —        |             |

## Response

| Status    | Body                        | Meaning |
| --------- | --------------------------- | ------- |
| `200`     | reference.ClearReferenceOut | ok      |
| `default` | problem-details             | refused |

`200` body — 4 fields.

| Field       | In   | Type            | Always | Description                                                                                                                                    |
| ----------- | ---- | --------------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| `cleared`   | body | boolean         | —      | Cleared is false when your org held no such override — which is not an error, it is the honest answer to a removal that had nothing to remove. |
| `key`       | body | string          | —      | Key is the entry named.                                                                                                                        |
| `overrides` | body | integer (int64) | —      | Overrides is how many your org still holds in this set.                                                                                        |
| `set`       | body | string          | —      | Set is the set cleared in.                                                                                                                     |

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

## Examples

**CLI**

```bash

```

**SDK**

**.ts**

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

const api = new ReferenceApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.riskClearReference({ set: 'set' });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = ReferenceApi(client).risk_clear_reference(set='set')
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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