Customers need more than model access: they need to know what every API key, customer, feature, and model costs, and cap risk before spend runs away.

Existing API-key monthly budgets stay in place; Spend Control adds workspace budgets, per-request max cost, and model allow/block controls.
Customers can pass customer_id and feature through headers or payload metadata for usage, billing, and anomaly review.
