Common questions
How fresh is the data?
We poll the market multiple times a second, pulled from public spot market sources. When a bid or ask changes, WebSocket subscribers see it right away.
What do bid, ask, and spread mean?
Bid is what buyers offer; ask is what sellers want. The spread is the gap between them, normal for any market. Mid is the midpoint, and it's what the candles, change, and ticker above use.
How do I keep my API key safe?
Send it in the X-API-Key header (or as a Bearer token) from your server, never from client-side JavaScript or a public repo. We don't accept keys in the query string, since those end up in logs and browser history. If a key leaks, rotate it from your client area and the old one stops working right away.
What happens if I cancel or a payment fails?
Your key keeps working until your plan lapses. If a renewal payment fails, the key is suspended and API calls return 403 payment_required until you reactivate. You won't lose any data or need a new key, it just turns back on once you pay.
Where do I get help?
Email support@<DOMAIN> or use the contact link in your client area. A real person will get back to you.
