# Billing

> Balance, top-ups, and the price list.

One prepaid Remyx balance, spent pay as you go. Scope: `billing:read` / `billing:write`. See [Billing](https://docs.remyx.ai/platform/configure/billing.md).

```
GET /api/v1.0/billing
```

Your balance, recent transactions, whether a grant covers you, Checkout availability, and the top-up presets and limits. A service token gets the price list instead.

```
POST /api/v1.0/billing/checkout
```

| Field | Type | Description |
| - | - | - |
| `amount_usd` | number | Between the minimum and maximum top-up returned by `GET /billing` |
| `success_url`, `cancel_url` | string | Optional return URLs; default to the Studio Account page |

Returns `{url, session_id, amount_usd}`; send the browser to `url`. `409` when Checkout is not configured on the server, `400` for an amount out of range, `403` for anything but a user-scoped token. The Stripe webhook at `/billing/stripe/webhook` credits the balance once per event.
