# Cap spend

> Keep more of your Claude plan for yourself, switch to an API key with a dollar cap, limit one ticket, and see what each pull request cost.

## Keep more of your weekly plan

Dobby stops starting work at this share of your week. The default is 95.

```bash title="Terminal"
dobby config set pacing.weekCap 80
```

```text title="dobby limits"
Running · 5-hour 34% (cap 60%) · week 49% of 80%
```

## Run on an API key

:::tip
The quickest way is `dobby init`. When Claude Code is not signed in, it asks "Plan or API key?".
:::

To set it up by hand:

1. Add the key to your secrets file.

   ```bash title="~/.config/dobby/secrets.env"
   DOBBY_API_KEY=<key>
   ```

2. Set the mode and the dollar caps.

   ```json title="config.json"
   { "billing": { "mode": "apiKey", "dailyUsd": 20, "weeklyUsd": 100 } }
   ```

3. Check the key. The "API key" row makes one small real call.

   ```bash title="Terminal"
   dobby doctor
   ```

Create the key inside a workspace in Console, or set the workspace id:

```bash title="Terminal"
dobby config set billing.workspaceId wrkspc_...
```

</details>

## Cap one ticket

Set the most one ticket may spend, by size, in percent of your week. A ticket over it goes to you.

```json title="config.json"
{ "ticketBudget": { "S": 1, "M": 3, "L": 8 } }
```

:::note
These numbers are an example. No ticket is capped until you set them.
