Crustdata — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Crustdata free to use?
Crustdata is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Crustdata need an API key?
Yes. Crustdata authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call Crustdata from browser JavaScript?
We could not confirm CORS support for Crustdata. Test it from a browser before relying on it client-side; if the request succeeds in curl but fails in the console, CORS is the reason.
Is Crustdata available over HTTPS?
Yes. Crustdata serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
