FAQ

Questions about this comparison

Which crypto exchange APIs have a test environment?

On the pages read on 5 November 2026, Binance, Bybit, Deribit, Gate and Hyperliquid publish separate test hosts. OKX and Bitget run demo trading through a header on the production REST host. Kraken has a self-service Derivatives demo and Spot test access on request. Coinbase Advanced Trade has a sandbox with fixed responses. None was found for BtcTurk, KuCoin, MEXC or Paribu.

Which exchanges offer a FIX API?

Binance (Spot), Bybit (Spot, by whitelist), Deribit and Kraken (through an account manager) document FIX. Coinbase's FAQ says FIX is not supported on Advanced Trade. It was not found on official pages for the other eight platforms.

How do exchange API rate limits differ?

Binance and Hyperliquid count weight per IP, with separate order or address limits. Bybit and OKX set limits per user per endpoint. Kraken's Spot REST API uses a counter per key, Deribit uses credits per sub-account, and KuCoin uses pools by VIP level. Going over can mean a retry header, a temporary ban or a closed session.

Is this page a ranking or a recommendation?

No. Rows are alphabetical, there are no referral links, and being listed here is not a recommendation. Fincode has no affiliation with any platform on this page.

What does "not found on official pages" mean?

It means the official pages we opened on that date did not show the item. It does not prove that the item does not exist, so check with the platform if it matters to your project.

How current is this page?

Every cell was read on 5 November 2026. The page is updated by hand when we check, so read the linked official page before you rely on a number.

Need software built on an exchange API?

Tell us the platform you use, what the software should do and your timeline. The exchange API integration page describes such work in general terms. For customers outside Türkiye, which platforms can be used depends on the law of your country and the platform's terms. For customers resident in Türkiye, we work with platforms on the Capital Markets Board's list that offer an API; being listed does not mean a platform is authorized. Fincode is a software company and does not provide investment advice, portfolio management or crypto asset services. Trades can lose money.
