# Models and credits questions

Separate model selection, Foxora credits, and external provider billing before diagnosing availability or cost.

## Which model should an API client use?

Call `GET https://api.foxora.ai/v1/models` and send a returned `id`. Do not hardcode a provider catalog that can change.

## Are credits the same as tokens?

No. Foxora credits are the customer-facing managed-service allowance. Token counters may appear in diagnostics, but they are not a second customer balance.

## Where can I see remaining usage?

Open **Settings → Account → Usage**, the hosted **Usage** page, or run `foxora usage`.

## What about BYOK?

A provider key uses that provider’s account, limits, and billing separately. Inspect both Foxora usage and the provider dashboard.

**Expected result:** you know which account funds the request and which live source reports its remaining allowance.
