Dudelytics — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Dudelytics free to use?
Dudelytics is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does Dudelytics need an API key?
No. We called Dudelytics on our last run with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call Dudelytics from browser JavaScript?
Not directly. Dudelytics did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Dudelytics available over HTTPS?
Yes. Dudelytics serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
