Bewertungen

I use Changelly crypto currency exchange for about a year and I want to admit a digital exchange’s list that is quite wide. I found tokens that I wanted to swap and buy on this platform and the rate was very good. Thanks! Keep moving forward.

I’ve been using Changelly for 3 years and I had an issue with a transaction only once. But the support reacted right away and I’ve got feedback from the support lady within like 20 min. Changelly is the biggest crypto exchange for instant swaps which provides deep liquidity (it’s important for the crypto exchange market). Thanks guys! You’re the best.

Awesome crypto exchange! But you can’t swap crypto for US dollars, only for another crypto. You can buy crypto for us dollar through Changelly. Crypto fees are reasonable, support works fast. I consider Changelly as the safest crypto exchange since they don’t hold users’ funds. Liked the UX.

Changelly is one of the biggest crypto exchangers with a decent mobile application. I swap my crypto coins here and get them within like several minutes.

Harold Simm

Love the Changelly crypto exchange platform because I can swap my coins really fast. I’ve been using it for several years and being a dedicated client. I wonder if i can get any more privileges besides the referral program :)

FAQ API

How do I get my API keys?

To get your API keys, just create an account on Changelly (or log in if you already have one) and send the following information at [email protected]: the email address that you have registered an account with; brief description of your project in which you are planning to integrate the Changelly API; the link to your project.

Is there an integration fee?

The Changelly API is free.

Can I use the Changelly API to exchange fiat-to-crypto?

You can exchange only crypto-to-crypto via our API. If you are interested in fiat payments, you might also like other Changelly affiliate tools, such as purchase/exchange widgets and buttons that are fiat-compatible and can be customized to your platform.

How do I earn money with Changelly API?

We offer our API partners an extra fee payment model: you are welcome to choose an extra fee that will be added on top of the Changelly exchange fee. The extra fee is going to be included in the rate shown to your clients. Typically, the extra fee is 0.1% and 5% per transaction.

What’s the difference between the Pure DeFi API and Exchange API?

Pure DeFi — a DEX aggregator with over 100 DEXs (decentralized exchanges) connected to it — provides users with the best prices and access to over 3600 tokens in the DeFi field. At the same time, the exchange is facilitated by a smart contract, which is open source. Thus, the blockchain itself ensures the reliability and transparency of the exchange.
Exchange API is a cross-chain platform that supports 140+ blockchains and enables crypto exchange via CEXs (centralized exchanges) with instant access to over 500 coins.

Can you show some examples of the Changelly API integration?

Such projects as Ledger, Trezor, Exodus, Coinomi, and many other notable crypto platforms utilize the Changelly API for an efficient and seamless workflow. See the full list of our partners here.

What if I have additional technical questions?
