That's expected behavior.
Hi Anton, I just realised that this actually exposes the bingKey. How can I prevent non authorised people from viewing and copying the bingKey?
You don't. You just need to configure your key to not allow any usage outside of your website.
I am glad I asked the question as my key was not secured. Thanks Anton I've changed the security on my bingKey now so it can only be used on my website.
GET api/server doesn't have security authorization. on the API reference indicating that this has got Basit Auth, but it is allowing us to read even without authorization.
