# Notifications

> Stay ahead of a low wallet balance with automatic email alerts.

Kalixo proactively emails your account when your **wallet balance falls below a threshold**,
so orders never fail for lack of funds.

## Low-balance email

<Steps>
  <Step title="We watch your balance">
    Balances are checked regularly against a configured low-balance threshold.
  </Step>

  <Step title="We email you on the way down">
    When a balance crosses **below** the threshold, we email your account address once.
    We won’t spam you on every check.
  </Step>

  <Step title="We re-arm after a top-up">
    Once you top up above the threshold, the alert resets and can fire again next time.
  </Step>
</Steps>

## Check your balance anytime

You can always read your balances on demand:

```bash theme={"dark"}
curl -X GET "https://api.kalixo.io/v2/wallet" \
  -H "x-api-key: $KALIXO_API_KEY"
```

```json Response theme={"dark"}
{
  "balances": { "EUR": 1234.56, "GBP": 196.01 },
  "lowBalance": false,
  "threshold": 100
}
```

<Info>
  Email alerts are the first notification type. HTTP [webhooks](/concepts/webhooks) for events
  such as `order.completed` and `balance.low` are planned - see the webhooks page for draft
  event shapes.
