| **Address**   | `https://api.hanzo.ai/v1/knowledge/files/{id}` |
| **Method**    | `DELETE`                                       |
| **Operation** | `delete_knowledge_files_by_id`                 |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`         |

Removes one of the caller's org files from the index — its table of
contents, passages, full-text rows, mentions and links — and its record. The
file is gone from every read when this answers: its listing, its contents,
search and retrieval. What the index held of it is removed after, a batch at
a time, so forgetting a file of any size answers at once. The object itself
stays in its bucket; delete it there. Drive calls this when it deletes a file.

## Request

1 field.

| Field | In   | Type   | Required | Description                                                   |
| ----- | ---- | ------ | -------- | ------------------------------------------------------------- |
| `id`  | path | string | yes      | ID is the file's id, as POST /v1/knowledge/files answered it. |

## Response

| Status    | Body                | Meaning |
| --------- | ------------------- | ------- |
| `200`     | knowledge.forgotten | ok      |
| `default` | problem-details     | refused |

`200` body — 1 field.

| Field | In   | Type   | Always | Description                             |
| ----- | ---- | ------ | ------ | --------------------------------------- |
| `id`  | body | string | —      | ID is the file whose index was removed. |

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

## Examples

**CLI**

`hanzo` has no subcommand for this operation — the CLI serves only what cloud's live route table confirms. Use HTTP or an SDK.

**SDK**

**.ts**

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

const api = new KnowledgeApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.deleteKnowledgeFilesById({ id: 'id' });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = KnowledgeApi(client).delete_knowledge_files_by_id(id='id')
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new KnowledgeApi(client).deleteKnowledgeFilesById();
```

**HTTP**

```bash
curl -X DELETE https://api.hanzo.ai/v1/knowledge/files/<id> \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **knowledge** through the `knowledge` tool, which names its 9 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_knowledge_connectors"
         }
       }
     }'
```
