# Authentication

Every request to the API must include your API key in the `x-api-key` header. Requests without a valid key are rejected.

## Get a key

Create and manage API keys in the [dashboard](https://dashboard.disasm.dev). One key works across every service on your plan.

## Base URLs

Each service has its own host:

| Service   | Base URL                       |
| --------- | ------------------------------ |
| DataDome  | `https://dd.antibotapi.com`    |
| Incapsula | `https://incap.antibotapi.com` |

## Making a request

Send the key as a header on every call:

```bash
curl -X POST https://dd.antibotapi.com/interstitial \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "device_check_link": "...", "device_check_page": "..." }'
```

The same header applies to every endpoint - see the [DataDome](/datadome/api-reference.md) and [Incapsula](/incapsula/api-reference.md) references.

## Responses

All endpoints return JSON. A successful call returns the solve data (and `success: true` where applicable); a failure returns `success: false` with an `error` message:

```json
{ "success": false, "error": "Error message explaining what went wrong" }
```

{% hint style="info" %}
Keep your API key server-side and treat it like a password - anyone with it can spend your balance.
{% endhint %}
