| **Method**    | `POST`                                               |
| **Operation** | `post_captable_rounds_by_id_close`                   |

Closes one of the caller org's fundraising rounds, recording the
close date and moving its status to CLOSED. Only an OPEN round can be closed:
a round that is already closed — like an id this org does not hold — is not
found. Closing a round does not change what was invested in it.

## Request

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

| Field       | In   | Type   | Required | Description                                             |
| ----------- | ---- | ------ | -------- | ------------------------------------------------------- |
| `id`        | path | string | yes      | ID is the round to close.                               |
| `closeDate` | body | any    | —        | CloseDate is the date to record the round as closed on. |
| `id`        | body | string | —        | ID is the round to close.                               |

## Response

| Status    | Body                     | Meaning |
| --------- | ------------------------ | ------- |
| `200`     | captable.captableUpdated | ok      |
| `default` | problem-details          | refused |

`200` body — 2 fields.

| Field     | In   | Type    | Always | Description                                                                |
| --------- | ---- | ------- | ------ | -------------------------------------------------------------------------- |
| `message` | body | string  | —      | Message is the human sentence the cap table wrote, e.g. "Company updated". |
| `success` | body | boolean | —      | Success is true when the update was applied.                               |

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

## Examples

**CLI**

```bash
hanzo captable rounds close <id>
```

**SDK**

**.ts**

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

const api = new CaptableApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postCaptableRoundsByIdClose({ id: 'id', closeDate: "<closeDate>", id: "<id>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = CaptableApi(client).post_captable_rounds_by_id_close(id='id', close_date="<closeDate>", id="<id>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new CaptableApi(client).postCaptableRoundsByIdClose();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/captable/rounds/<id>/close \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "closeDate": "<closeDate>",
       "id": "<id>"
     }'
```

**MCP**

MCP reaches **captable** through the `captable` tool, which names its 30 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_captable_classes"
         }
       }
     }'
```
