## Prerequisites

1. CLI installed and logged in via OAuth (see setup skill).
2. Billing features require OAuth login -- API Key mode may not have access.

## Commands Reference

## Guidance

- Billing commands require OAuth login, not API Key authentication.
- When the user asks about costs or spending, use `billing usage` with an appropriate time range.
- To bind a credit card, direct the user to the Zilliz Cloud web console -- card binding is not available via CLI for security reasons.
