FraudCoins — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is FraudCoins free to use?
FraudCoins 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 FraudCoins need an API key?
No. We called FraudCoins 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 FraudCoins from browser JavaScript?
Yes. FraudCoins returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is FraudCoins available over HTTPS?
Yes. FraudCoins serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
