We are thrilled to announce that we have launched the upgraded OpenOcean DEX API 3.0 for everyone to use! The API 3.0 is an easy-to-use API for individuals or projects that needs non-custodial functions such as price quotes, token swaps, transfers, and trading records tracking. This article will explain the five reasons that make the OpenOcean API 3.0 best-in-class for multi-chain swaps.

If you are new here, OpenOcean is a smart DEX aggregator that integrates major DEXes across 16 public chains. We offer a free, efficient, and seamless DeFi experience by optimizing trading for maximum returns with an intelligent routing algorithm.

What makes the OpenOcean API the best choice?

• Best rates: The API is connected to the OpenOcean Atlantic version, which offers the best rates for supported blockchains and token pairs. The Atlantic version provides a superior algorithm for finding the best pricing route based on multiple parameters, including price, gas fee, slippage, etc.
• Support the most networks and DEXes: OpenOcean API is now available on all 16 integrated blockchains — Ethereum, BNB Chain, Polygon, Avalanche, Fantom, Solana, Arbitrum, Terra, Optimism, Moonriver, Gnosis, Boba, HECO, OEC, Ontology, Tron, with over 120 liquidity sources and has included more than 1,400 tokens in the API. Users can quote and find the best prices from integrated DEXes. Additionally, we will continue to update new integrations to the API as the team expands to more blockchains and liquidity sources.
• Fast response time: We now have a competitive edge in response time of 200ms on average, allowing instant price quoting.
• Developer-friendly: OpenOcean offers a detailed API & SDK guideline to assist the integration process. Also, we have committed tech support to help with any integration-related issues. Lastly, OpenOcean can provide customized API parameters to our partners.
• Free to use: OpenOcean does not charge fees for the API service and no additional cost while using our protocol.

Who are the potential users?

The OpenOcean API targets a wide range of users and projects, specifically for users who have already developed a UI system that does not require an extra wallet integration. We recommend the OpenOcean API for the following users:

• Developers interested in making their own DeFi project or trading platform but do not have the resources to maintain a complete swap service. In that case, our API provides a series of stable and reliable interfaces to help build your project.
• Aggregators who want as many liquidity sources as possible: OpenOcean API is a core product to improve your user experience with better trading speeds and lower trading costs — for instance, Rango Exchange recently integrated OpenOcean API to power up their swap function on Fantom network.
• Crypto wallets or tracking services that want to provide the best prices to users: OpenOcean API can provide a whole set of quoting, swapping, and tracking functions. We highly recommend deploying the interface into your server to build up an entire management system and get enterprise-class data service.

Several projects have adopted our API to provide the price quoting function as the core service, such as Mask, Li Finance, and RangoExchange. Additionally, ONTO Wallet implemented our API for the swap function.
