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.
