0x has announced the private beta launch of its Cross-Chain API, a developer-focused solution designed to simplify token swaps across more than 15 blockchains through a single integration. The new API is intended to support applications that rely on programmatic trading, automated treasury management, and cross-chain execution across EVM-compatible networks and Solana. By abstracting away the technical complexity of interacting with multiple blockchains, the company aims to help developers focus on building intelligent execution strategies rather than managing fragmented infrastructure.
Founded in 2017, 0x has positioned itself as a core infrastructure provider for decentralized trading. The platform enables companies to embed crypto trading functionality directly into their applications through APIs and real-time analytics. According to the company, more than 500 teams currently rely on its technology, with cumulative trading volume exceeding $200 billion and end-user reach extending to over 14 million users across major consumer-facing crypto applications.
Addressing Cross-Chain Execution Challenges
The introduction of the Cross-Chain API reflects growing demand for reliable and predictable execution across multiple blockchains. 0x’s product leadership has indicated that developers building automated trading systems and treasury workflows increasingly require fast and consistent cross-chain functionality that is easy to integrate. The new API is designed to meet those needs by consolidating liquidity sources and routing transactions through multiple bridge providers.
The system automatically optimizes each transaction based on developer-defined preferences, such as prioritizing price efficiency or faster settlement. This approach enables so-called bridge-and-swap transactions that can settle in under a minute for common token pairs, while appearing as a single, seamless action to the end user. The API also allows developers to stream quotes as soon as they are generated, improving transparency and reducing support overhead through better error tracking.
Enabling AI-Driven and Automated Workflows
0x’s leadership has framed the Cross-Chain API as a critical enabler for autonomous systems, including AI-driven trading agents. Company co-founder Will Warren has explained that automated agents are designed to identify opportunities rather than individual blockchains, making abstraction layers essential for their operation. By removing chain-specific complexity, the API is positioned as a foundational tool for developers building AI agents capable of executing strategies across multiple networks with a single API call.
The Cross-Chain API includes several core capabilities, such as near-instant cross-chain token swaps, intelligent routing for automated execution, and access to detailed documentation and integration guides. These features are intended to support both experimental and production-grade deployments.

Alignment With Emerging Payment Standards
The launch also comes amid broader industry efforts to standardize crypto-native payment and authentication flows for automated commerce. 0x has stated that its Cross-Chain API is designed to integrate with emerging standards, including stablecoin-based payment protocols and agent-focused frameworks developed by major technology and crypto firms. The company already supports swap functionality within developer tools offered by Coinbase, and it is aligning the new API with initiatives from Google and OpenAI focused on agent-based commerce.
This forward-compatible approach is intended to ensure that developers building on 0x today can adapt to future autonomous systems without significant re-engineering, as AI agents become more prevalent in digital commerce.
Market Outlook and Availability
Industry research from McKinsey has suggested that AI agents could mediate trillions of dollars in global commerce annually by the end of the decade. Such projections underscore the importance of fast, dependable, and scalable cross-chain infrastructure as automated systems take on a larger role in financial activity.
The Cross-Chain API beta is scheduled to become available for developer integration starting February 25, 2026. Through this release, 0x is seeking to reinforce its role as a foundational layer for decentralized trading while addressing one of the most persistent challenges in the blockchain ecosystem: fragmented liquidity across an increasingly multi-chain environment.
