# Nordstern > The only swap API with full market coverage Nordstern is a DEX aggregator API. It lets developers and applications find and execute optimal token swap routes across EVM-compatible blockchains. Nordstern is a DEX aggregator API that finds and executes token swap routes across EVM-compatible blockchains. Developers submit an input token, an output token, and an amount, and receive the best split route with a ready-to-submit transaction. The service is built for wallets, trading interfaces, DeFi protocols, and arbitrage bots. Nordstern queries available liquidity sources and simulates each route before returning it, which reduces failed transactions. It supports rebasing, taxed, and other non-standard tokens, and it adds new tokens and chains continuously. The API needs no key, registration, or subscription and charges no protocol fee on swaps. Decentralized exchanges and liquidity providers can integrate as liquidity sources, and integrators can apply their own fee on top of swaps. Nordstern is used by application developers, solvers, and DeFi teams that need swap execution across many networks. - Type: Protocol - Sector: Finance - Status: Active - Founded: 2025-08-01 - Profile: https://thegrid.id/profiles/nordstern ## Products - [Nordstern Swap API](https://thegrid.id/profiles/nordstern): Nordstern Swap API is a DEX aggregator service that routes token swaps across EVM-compatible networks.
