This means that you will have to top-up your balance before you can send out your messages and that the costs of your usage will be deducted from your balance. The exact costs differ per country and can be found on our [Pricing page](https://www.messagebird.com/en/pricing/). To ensure that you never run out of credits we have two helpful features that can help out: * [Low-balance warning:](/connectivity-platform/payment-billing/setting-low-balance-notifications.md) You are notified when your balance goes below a certain amount. * [Auto-order](/connectivity-platform/payment-billing/how-to-set-up-auto-top-up.md): We will automatically create a new order for you when your balance goes below a certain amount. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.bird.com/connectivity-platform/payment-billing/prepaid-account-billing.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
