What's a DEX API?

OKX Wallet is a leading global digital asset wallet built on decentralization principles. It provides self-custody services and decentralized exchange aggregation, supporting both EVM-compatible and non-EVM chains such as Solana, Sui, and TON.

The OKX Wallet API includes two core API modules that support spot trading, transaction simulation and broadcasting, as well as real-time market and on-chain data:

  • DEX API: Powered by an advanced smart routing algorithm, the DEX API helps optimize trades by identifying the best quotes and the most efficient swap routes across supported networks.

  • Market API: Provides comprehensive multi-market and on-chain data, including token information, trades, transactions, and account data.

Together, these APIs cover the essential modules of decentralized trading systems. They enable developers to simplify integration and reduce both development time and costs.

This documentation is intended to help enterprises and developers build a wide range of Web3 trading services and applications, such as:

  • swap applications

  • market data platforms

  • Web3 wallets

  • trading bots
