# 0x > Embed swaps in your onchain app 0x is a company that provides infrastructure for on-chain token trading. It offers APIs that let developers embed swaps, liquidity aggregation, and gasless trading into wallets, exchanges, and apps. 0x is a company that builds application programming interfaces for on-chain token trading and settlement. Its infrastructure lets developers embed swap functionality directly into wallets, exchanges, and other financial applications without operating their own liquidity or matching systems. The offering is aimed at wallet providers, exchanges, and application developers who want to add trading functionality without building it from scratch. The underlying protocol aggregates liquidity from many independent sources and routes trades to find pricing across them, rather than relying on a single order book or pool. It also supports gasless transactions, where the cost and complexity of on-chain execution is abstracted away from the end user, and cross-chain trading that lets a token on one network be exchanged for a token on another. The product suite is organized around a Swap API as the flagship offering, alongside additional APIs for gasless trading and trade analytics that give integrators visibility into trading activity. These tools are used by wallet providers, centralized exchanges, and decentralized application developers to bring token trading features to their own end users. Its technology has been integrated by a range of consumer wallets and trading applications across the industry. - Type: Company - Sector: Infrastructure - Status: Active - Founded: 2017-02-01 - Profile: https://thegrid.id/profiles/0x ## Products - [0x Swap API](https://thegrid.id/profiles/0x): 0x Swap API is a DEX aggregation service that lets developers embed token swap functionality directly into applications, wallets, and exchanges. It aggregates liquidity from multiple decentralized exchanges and market makers and applies smart order routing to find optimal trade execution paths. The API returns transaction-ready quotes and calldata across multiple EVM-compatible blockchains, and supports built-in monetization for integrating platforms. (DEX Aggregator, Live, Main Product) - [0x Gasless API](https://thegrid.id/profiles/0x): 0x Gasless API is a developer tool that enables token swaps without requiring users to hold native chain tokens for gas. It sponsors transaction fees on behalf of end users by abstracting gas payments and approvals into the backend, covering both gasless approvals and gasless swaps in a single flow. The API integrates into wallets and applications to remove a common onboarding friction point for users new to on-chain trading. (Developer Tooling, Live) - [0x Trade Analytics API](https://thegrid.id/profiles/0x): 0x Trade Analytics API is a data service that indexes on-chain trading activity processed through 0x infrastructure. It provides query access to historical trade volumes, pricing, and execution details across supported blockchains for monitoring and reporting purposes. Developers use it to build trade insight dashboards and analytics features into their own applications. (Pricing Data API, Live) - [0x AI Skill](https://thegrid.id/profiles/0x): 0x AI Skill is a packaged instruction set for AI coding agents that provides a complete token swap workflow using 0x APIs. The skill selects the appropriate token approval flow, queries live 0x documentation for unknown tokens and error resolution, and enforces safety checks before transaction submission. It is compatible with multiple AI-assisted development environments and is paired with an MCP server that gives agents on-demand access to current 0x documentation and API references. (Skills, Live) - [0x Cross-Chain API](https://thegrid.id/profiles/0x): 0x Cross-Chain API is a bridge aggregation service that provides a single integration for moving tokens across multiple blockchains. It discovers and streams available bridge routes, lets applications execute a swap-style bridging flow, and tracks the status of in-flight cross-chain transactions. The API consolidates routing, bridging, and tracking that would otherwise require multiple vendor integrations, and is currently offered through private beta access. (Open Beta) - [0x Solana API](https://thegrid.id/profiles/0x): 0x Solana API is a swap infrastructure product that generates swap instructions for tokens on the Solana network, returning versioned transaction data ready to sign and submit. It extends 0x liquidity aggregation and routing capabilities to a non-EVM blockchain, enabling developers to embed Solana token swaps into their applications. Access to the product is currently available through a priority access program. (Early access) ## Assets - [0x Protocol Token (ZRX)](https://thegrid.id/profiles/0x): ZRX is the governance token of the 0x Protocol, an on-chain infrastructure for token swaps. Holders stake ZRX to vote on 0x Improvement Proposals and treasury actions, and can delegate stake to market maker pools to earn liquidity rewards. Staking pools let ZRX holders amplify governance influence while market makers gain incentives without added price exposure to the token.
