See what your agents use and what it costs. OpenOrange connects model and service activity to the people, projects, and work behind it.

Every charge shows who and what it was for, so you know where the money goes.

## Key capabilities

- One prepaid balance in dollars for models, services, and compute (100 JU = $1).
- See which people, agents and models drive your costs.
- No OpenOrange fee on calls with your own provider keys.

## One prepaid balance

One balance in dollars covers models, services and machines for all your Sunports, and the Billing page shows where it goes.

## Know who spent what

Follow every charge to the person, agent or API key behind it, and set daily, weekly and monthly limits.

## Your own provider keys

Bring your own provider keys and see the same usage, with no OpenOrange fee.

## Questions

### Can I see what drives my costs?

Yes. Connect costs to people, agents, API keys, models, requests, and connected services. Price history and usage details help explain spending over time.

### Can cache savings be explained?

Yes. Observability shows each model’s prompt-cache hit rate, the tokens read from and written to the cache, and what caching saved.
