College ROI — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is College ROI free to use?
College ROI 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 College ROI need an API key?
No. We called College ROI on 2026-09-18 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 College ROI from browser JavaScript?
Not directly. College ROI 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 College ROI still working?
Yes, as of 2026-09-18. Our automated check reached College ROI and recorded a 100% reliability score with a median response time of 774 ms. We re-check on a schedule, and this page updates with the result.
Is College ROI available over HTTPS?
Yes. College ROI serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
