Frequently asked questions
Quick answers to the most common support requests.
My API key returns 401 INVALID_API_KEY. What should I check?
Make sure you send the key in the
Authorization: Bearer <API_KEY> header,
not in the query string. Confirm that the key is active on your dashboard and attached
to a plan with enough quota. If you regenerated the key, update it everywhere in your code.
How are rate limits enforced?
Each plan has a daily request quota and a per-second soft limit. If you exceed the limit,
the API may return HTTP 429 TOO_MANY_REQUESTS. Implement retry logic with exponential
backoff and avoid sending large bursts of requests in a single second.
Can I use Qorex data for a commercial trading platform?
Yes. The Starter and Pro plans are suitable for bots and small platforms.
Exchanges, brokers and prop firms should contact us about an Enterprise agreement,
which includes SLAs, higher limits and dedicated infrastructure.
How do I upgrade or downgrade my subscription?
You can change your plan from the billing section of your dashboard.
Plan changes take effect immediately, and any prorated credit will be automatically
applied to your next invoice.
Do you offer sandbox or demo keys?
Every new account starts with a Free plan that gives you limited live data,
ideal for testing integrations. If you need a dedicated sandbox cluster,
open a ticket and our team will discuss Enterprise options.
