On February 25, 2026, 0x opened private beta access to its Cross-Chain API. The company develops decentralized exchange infrastructure for crypto applications. The new product allows developers to perform token swaps across more than 15 blockchains, including major EVM networks and Solana, through a single integration.
The API is built to address liquidity fragmentation between chains. It aggregates liquidity and routes transactions through various bridging providers. The system can optimize swaps based on price or execution speed, depending on the developer’s settings.
Developers can stream quotes as they become available and monitor errors through enhanced tracking tools. The API is provided as a REST interface with documentation and integration guides published on the company’s website.
The release comes as new payment standards for automated systems are emerging. These include Coinbase’s x402, Google’s AP2, and OpenAI’s Agentic Commerce Protocol. 0x states that the Cross-Chain API is designed to integrate with such frameworks.
