Ogmios is a translation service written in Haskell running on top of cardano-node. It offers a JSON-WSP interface through WebSockets and enables clients to speak Ouroboros' mini-protocols via remote procedure calls over JSON. Ogmios is very lightweight too and can be deployed alongside relays to create entry points on the Cardano network for various type of applications (e.g. wallets, explorers, chatbots, dashboards...).
