One line to switch

The wire format is OpenAI's, so moving is a base URL change in code you have already written. Every SDK works unmodified.

Budgets that actually stop

Per-key spend caps enforced before the request reaches a provider, not reported to you the morning after an agent loop ran all night.

Attribution you can bill against

Every call recorded by key and by model, priced across all five token dimensions including cache reads and reasoning.

Prepaid, so there is no invoice shock

Start on free credit, then buy more when you need it. No monthly surprise and no credit line to reconcile.
