Question: i am using this code in order to get persons info by email

to post it on web page

In API documentation (<https://dashboard.clearbit.com/docs?shell#oauth>) http request looks like this

```html
HTTP REQUEST
GET https://person.clearbit.com/v2/combined/find?email=:email
```

I am try to do this in PHP (p.s. I hid my key in the example) 

```html
<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "https://person-stream.clearbit.com/v2/combined/find?email=alex@clearbit.com'");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("-u: api-key-here*** "));
$result = curl_exec($curl);
curl_close($curl);
print($result);
?>
```

But this what i get 

```html
{ "error": { "type": "auth_required", "message": "Authentication is required for this action. Sign up at https://clearbit.com" } }
```

What i am doing wrong here?

Thank you.

Answer: 
You missed something here, Angular needs double curly braces to render scope variables in the template (when you won't use it in the directive, such as ngIf, etc.):

```
<div *ngIf="artist.images.length > 0">
   <div style="background-image: url("{{ artist.images[2].url }}")">
   </div>
</div>

```
This is probably what you're looking for:

```
<div *ngIf="artist.images.length > 0">
    <div ng-style="{'background-image': 'url('+artist.images[2].url+')'}"></div>
</div>

```
