Check out what the world has to say about ChangeNOW


Are cross-chain swaps available?
Yes – every coin or token available on ChangeNOW can be exchanged for any other available currency, including cross-chain swaps.
How many exchange pairs do you have?
Within our list of 900+ assets, all coins and tokens are inter-exchangeable, meaning there are hundreds of thousands of exchange pairs available. New ones appear every time we add a new asset.
We source liquidity from 10 different CEXes and DEXes, ensuring that the liquidity flow is uninterrupted and you always receive the best possible rate.
How can I track the API status and coin’s availability?
Please consult our Status Page for tracking the uptime of our public API, as well as the status of supported assets.
You can also subscribe to specific events you are interested in, so we can update you on their progress.
If you already use our exchange API, you can also see any coin’s status with our Available Currencies endpoint.
What is an API key?
An API key is your unique identifier that grants authorized access to the API, allowing you to integrate ChangeNOW exchange service. The API key is essential for securely accessing and interacting with ChangeNOW's API. We emphasize the importance of secure API key management, ensuring that the keys are unique, random, and non-guessable, and securely stored within user accounts.
Where do I get my API key?
Join our Partners Program by signing up here. Once you sign up, you will be able to see your API key in Profile details. Use your API key to integrate our API solution, and keep it handy if you need to request a percentage change or enabling Fixed Rate.
