# Environments & Endpoints

> Base URLs, health check, authentication, and server location for the AX API.

## Environments

AX provides two environments:

| Environment | Base URL                                         |
| ----------- | ------------------------------------------------ |
| Production  | `https://gateway.architect.exchange/api`         |
| Sandbox     | `https://gateway.sandbox.architect.exchange/api` |

Use **sandbox** for development and testing. Use **production** when you are ready to trade with real funds.

## Health Check

Both environments expose a public health endpoint that requires no authentication:

```
GET /health
```

Example: `https://gateway.architect.exchange/api/health`

Use this to verify connectivity or check whether the service is up.

## Authentication

All API endpoints except `/health` require an API key. Pass your key in the `Authorization` header:

```
Authorization: Bearer <your-api-key>
```

To generate an API key, see [Create API Key](/api-reference/user-management/create-api-key).

## Server Location

The production environment runs on AWS **`eu-west-2`** (London).
