# Authentication

All Aterio API endpoints require an API key for access. This key must be included in the request header using the `x-api-key` field. API keys are issued to verified partners and customers.

#### EXAMPLE

To authenticate a request, include the following header:

```bash
x-api-key: your-api-key
```

#### SAMPLE REQUEST

{% tabs %}
{% tab title="Bash" %}

```bash
curl --request GET \
  --url https://api.aterio.io/v1/selected-endpoint?param1=value1&param2=value2 \
  --header 'x-api-key: your-api-key'
```

{% endtab %}

{% tab title="Javascript" %}

```javascript

fetch("https://api.aterio.io/v1/selected-endpoint?param1=value1&param2=value2", {
  method: "GET",
  headers: {
    "x-api-key": "your-api-key"
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error("Error:", error));
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

response = requests.get(
    "https://api.aterio.io/v1/selected-endpoint",
    headers={"x-api-key": "your-api-key"},
    params={"param1": "value1"}
)

data = response.json()
print(data)
```

{% endtab %}
{% endtabs %}
