Detaches a hostname and releases the claim.

It drops the host from the app's ingress and releases any custom claim on it, so
the name becomes claimable again — by this org or any other. Answers 204.

The default host is permanent and cannot be removed: that is 400, not 404. A host
that is neither attached nor claimed here is 404. Requires a validated principal;
401 without one.

## Request

3 fields.

| Field     | In   | Type   | Required | Description                                                        |
| --------- | ---- | ------ | -------- | ------------------------------------------------------------------ |
| `project` | path | string | yes      | Project is the project the application lives under, from the path. |
| `app`     | path | string | yes      | App is the application's slug, from the path.                      |
| `host`    | path | string | yes      | Host is the hostname, from the path.                               |

## Response

| Status    | Body            | Meaning    |
| --------- | --------------- | ---------- |
| `204`     | —               | no content |
| `default` | problem-details | refused    |

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

## Examples

**CLI**

```bash
hanzo platform projects apps domains rm <project> <app> <host>
```

**SDK**

**.ts**

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

const api = new PlatformApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.deletePlatformProjectsByProjectAppsByAppDomainsByHost({ project: 'project', app: 'app', host: 'host' });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = PlatformApi(client).delete_platform_projects_by_project_apps_by_app_domains_by_host(project='project', app='app', host='host')
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new PlatformApi(client).deletePlatformProjectsByProjectAppsByAppDomainsByHost();
```

**HTTP**

```bash
curl -X DELETE https://api.hanzo.ai/v1/platform/projects/<project>/apps/<app>/domains/<host> \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **platform** through the `platform` tool, which names its 38 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": "get_build"
         }
       }
     }'
```
