ChangeNOW API
Blockchain · Trading
ChangeNOW is a non-custodial instant cryptocurrency exchange service that provides an API for embedding crypto-to-crypto swaps directly into wallets, apps, and platforms. Unlike centralized exchanges (Binance, Coinbase) that require user account creation, KYC verification, and custody of funds on the exchange, ChangeNOW operates as a swap service: users provide their source asset and destination wallet address, ChangeNOW executes the exchange across its liquidity network, and the converted asset lands directly in the user's own wallet.
ChangeNOW API Highlights
ChangeNOW API is verified for developer integrations in Nigeria and across African markets, providing documented endpoints, sandbox testing, and developer support.
