​
Cost preflight

There is no separate pricing endpoint. Every generation can be previewed for free by passing getCost: true (SDK and MCP) or --cost (CLI) on the generate call. The preflight takes the same parameters as the real call, so the quote matches the charge. See Account & Billing.

​
Usage attribution

Spends made with an API key are attributed to that key. Per-key usage is visible in the API Keys view in the app.
