# Alibaba Cloud CLI Cost Estimation Get an exact price quote for a CLI operation **without executing it**. The quote comes from the same pricing source as the trade system: for operations that produce an immediate order, the quoted amount equals the order amount you would actually pay (verified across new purchases, spec upgrades, and bandwidth changes — quote and bill match to the cent). This is the **pre-execution** half of cost management. The post-hoc half (bills already incurred) is `aliyun bssopenapi QueryAccountBill` — see the reconciliation section below. ## Requirements - Alibaba Cloud CLI ≥ 3.4.2 (`aliyun version`) - Product plugins up to date (`aliyun plugin update`) ## The Agent Rule: Quote Before Chargeable Execution When you are about to execute an operation that creates, resizes, renews, or otherwise changes billable resources: 1. **Check** whether the API supports quoting (see Discovery below). 2. **Quote** it by appending `--estimate-cost` to the exact command you intend to run. 3. **Present** the amount to the user as part of the confirmation, e.g. "This will execute `ModifyPrepayInstanceSpec` — estimated charge ¥28.89 (prorated upgrade delta). Proceed?" 4. **Execute** only after confirmation, by removing `--estimate-cost` from the same command. Never silently execute a chargeable operation when a quote was obtainable. `--estimate-cost` is always safe to add: it only quotes, never executes, and changes nothing in the account. **Multi-ste...
