0x Opens Cross-Chain API Beta

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 execute token swaps across more than 15 blockchains through a single integration, including major EVM networks and Solana.

The API is built to address liquidity fragmentation between chains. It aggregates liquidity and routes transactions through several bridge providers. The system can optimize swaps for price or execution speed, depending on developer settings.

Developers can stream quotes as soon as they are available and monitor errors through improved tracking tools. The API is delivered 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 x402 by Coinbase, AP2 by Google, and the Agentic Commerce Protocol from OpenAI. 0x states that its Cross-Chain API is designed to integrate with such frameworks.
