Prepaid credit, pay as you go. Each request costs what the model’s price says, and the request log shows exactly what it counted.

## Credit

- Add credit by card under [Billing](https://zurelay.com/app/billing), from $10. It’s shared by every key in the workspace.
- Credit you buy doesn’t expire while your account is open.
- Auto-recharge, under [Billing](https://zurelay.com/app/billing) → Payment method: save a card (it goes to Stripe, never to us) and we add a set amount whenever the balance falls below your threshold, at most once every two minutes and ten times a day, with a receipt by email. A declined card pauses it, and the owners and admins are told why.
- When the balance runs out, requests are refused with `402 insufficient_quota` until you add more. The balance is checked before each request, so the last one can take it slightly below zero; the next top-up covers that.

## What a request costs

| Kind | Billed by |
| --- | --- |
| Chat | Input tokens and output tokens, at the model’s price per million. Cached input at the cached price where the model has one. |
| Images, PDFs, audio, video in a message | The input tokens the model counts for them (see Images, PDFs, audio and video) |
| Reasoning | Thinking tokens count as output tokens |
| Images made | Per image, by resolution |
| Videos | Per second, by resolution |

Prices are on the [models page](https://zurelay.com/docs/models). Each model’s own page shows the lab’s list price beside ours.

## What’s free

- Failed requests, and requests refused by a key’s rules or the balance.
- Images a model declined, and failed videos.
- Listing models and counting tokens.
- The instructions we add to keep models answering as themselves: you’re only billed for what you send and receive.

A stream you cancel is billed for its input and the tokens generated up to that point. With smart routing, a request answered by an alternative is billed at the alternative’s price.

## Where to see it

- The [request log](https://zurelay.com/app/requests): every request with its model, tokens, cost and speed.
- Each API key’s spend today and this month on the API keys page.
- Your credit history and receipts under Billing.
