# Environments

Namify provides two fully isolated environments. Same API surface, same endpoints, same response shapes. The only differences are real-world impact and billing.

## <Icon icon="pencil" />  Sandbox

| **Variable**       | Description                                                         |
| :----------------- | :------------------------------------------------------------------ |
| **Base URL**       | [https://dev.namify.host/api/v1](https://dev.api.namify.tech/v1)    |
| **Key prefix**     | nk\_test\_\*                                                        |
| **Billing**        | No charges. All transactions succeed without debiting your account. |
| **Registrations**  | Simulated. Nothing is submitted to ICANN or any registry.           |
| **Availability**   | Most standard TLDs return as available.                             |
| **Webhooks**       | Fire normally. Test your integration end-to-end.                    |
| **Data retention** | Purged every 24hrs. Do not rely on sandbox for persistence.         |
| **Pre-funded**     | Sandbox accounts come with simulated credit. No setup required.     |

## <Icon icon="code" />  Production

| **Variable**      | Description                                                                            |
| :---------------- | :------------------------------------------------------------------------------------- |
| **Base URL**      | [https://namify.host/api/v1](https://api.namify.tech/v1)                               |
| **Key prefix**    | nk\_live\_\*                                                                           |
| **Billing**       | Real charges. Invoiced monthly or per-transaction<br />based on your commercial terms. |
| **Registrations** | Live ICANN registrations. Domains are active on the internet.                          |
| **Webhooks**      | Fire normally.                                                                         |

## Switching environments

Swap two environment variables. No code changes:

```shellscript theme={null}
# Sandbox
NAMIFY_BASE_URL=https://dev.namify.host/api/v1
NAMIFY_API_KEY=nk_test_...

# Production
NAMIFY_BASE_URL=https://namify.host/api/v1
NAMIFY_API_KEY=nk_live_...
```

## Migration path

Build and test against sandbox. When your integration passes the Go-Live Checklist, swap in production credentials. The API behavior is identical the only change is that domains become real and billing begins.
