+# urlscan
+
+The `urlscan` connection can be used to access URLScan resources.
+
+```hcl
+connection "urlscan" "my_urlscan" {
+  api_key = "11111111-e127-1234-adcd-59cad2f12abc"
+}
+```
+
+## Arguments
+
+| Name      | Type   | Required? | Description |
+| --------- | ------ | --------- | ----------- |
+| `api_key` | String | Optional  | API Key     |
+
+All arguments are optional, and a `urlscan` connection with no arguments will behave the same as the [default connection](#default-connection).
+
+## Attributes (Read-Only)
+
+| Attribute | Type | Description                                                                        |
+| --------- | ---- | ---------------------------------------------------------------------------------- |
+| `env`     | Map  | A map of the resolved connection-related environment variables (`URLSCAN_API_KEY`) |
+
+## Default Connection
+
+The `urlscan` connection type includes an implicit, default connection (`connection.urlscan.default`) that will be configured to set the `api_key` to the `URLSCAN_API_KEY` environment variable.
+
+```hcl
+connection "urlscan" "default" {
+  api_key = env("URLSCAN_API_KEY")
+}
+```
