# Authentication

### Base Endpoint

Inspector APIs are hosted on the following base URI:

```
https://app.inspector.dev/api
```

### Include the key

In order to use the API you should authenticate your request by including your API key as a bearer token value in the request's headers:

```
Authorization: Bearer API_KEY_HERE
```

{% hint style="info" %}
If you don't have an API key, you can create a new one in just a few clicks: <https://app.inspector.dev/account/api>
{% endhint %}

### Recommended Headers

Make sure you have the following content type headers set on every request:

```
Accept: application/json 
Content-Type: application/json
```

### Error codes

Inspector uses conventional HTTP response codes to indicate the success or failure of an API request. The table below contains a summary of the typical response codes:
