# Buy — Simulator.Company

Use the live calculator on [simulator.company/buy](https://simulator.company/buy)
to size and purchase a license. Agents can fetch tariffs directly:

```
GET https://simulator-proxy.makarichev-dmitry.workers.dev/license/tariffs
```

Each tariff returns:

- `id` — stable identifier.
- `name` — public tier name.
- `rps` — peak requests per second.
- `storageGb` — included storage.
- `priceUsdMonth` — base monthly price.

To create a Stripe checkout session:

```
POST https://simulator-proxy.makarichev-dmitry.workers.dev/license/checkout
Content-Type: application/json

{ "tariffId": "<id>", "email": "buyer@example.com" }
```

The response is `{ "url": "https://checkout.stripe.com/..." }`.

## Pricing model in plain language

- Pricing scales with **RPS** (peak requests per second), not seats.
- Storage is included up to a tier-specific limit; overage is metered.
- Cloud, On-Prem and Enterprise deployment options are available — see
  [/license.md](/license.md).
