ChartBytes — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is ChartBytes free to use?
ChartBytes 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 ChartBytes need an API key?
No. We called ChartBytes on 2026-09-27 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 ChartBytes from browser JavaScript?
Yes. ChartBytes 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 ChartBytes still working?
Not at our last check on 2026-09-27. ChartBytes did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is ChartBytes available over HTTPS?
Yes. ChartBytes serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
