## What to check in Studio

| Your check | Studio location |
| --- | --- |
| Development allowance usage for `debugKey` requests | Account area → Billing → Studio plan |
| Runtime credit balance | Account area → Billing → Runtime credits |
| Project limits | Project → Settings → Budget & limits |
| Reports for your development requests | Project → Monitoring → Logs → Filters → Usage type → Development · Subscription |

Croche runs the model for you; production usage is charged to your project's credit. Development allowance and Runtime credit are separate. Check the view that matches your app's credentials. Event allowances are listed in the [hackathon guide](../hackathon.md).

For a terminal view of project usage, use `croche projects usage PROJECT_ID --period week`; see the [CLI guide](../cli.md).

## Errors your app can receive

A turn can fail with a usage-related reason:

| Error code | Developer action |
| --- | --- |
| `development_allowance_exhausted` | Check the development allowance in Studio before another development request |
| `project_budget_exhausted` | Check the project's Budget & limits before another request |

Keep the error's code and message available in your app's error handling. Show a useful failure state rather than leaving the UI waiting for a reply. Do not repeatedly send new requests to test whether a limit has cleared; review the relevant Studio setting first.
