Reads a schedule said in words — "every 5 minutes", "weekdays at 8:30",
"every monday at 9am", "tomorrow at 7pm", "in 20 minutes", or a five-field
cron expression — in your time zone, and answers the schedule an automation
takes, said back in plain words, with when it would first run. Nothing is
created: send the schedule to POST /v1/auto/automations. A phrase that no rule
reads is read by a model; a phrase that names no schedule answers 422.

| Field  | In   | Type   | Required | Description                                                       |

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

## Examples

**CLI**

```bash
hanzo auto cron
```

**SDK**

**.ts**

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

const api = new AutoApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postAutoCron({ text: "<text>", tz: "<tz>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = AutoApi(client).post_auto_cron(text="<text>", tz="<tz>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new AutoApi(client).postAutoCron();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/auto/cron \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "text": "<text>",
       "tz": "<tz>"
     }'
```

**MCP**

MCP reaches **auto** through the `auto` tool, which names its 26 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_auto_automations"
         }
       }
     }'
```
