Koios TypeScript Client
Koios Typescript Client is a REST Client library which allows interacting with Koios Server Instances. Koios TypeScript Client Library is based on Koios Elastic Query Layer for Cardano Node by Cardano Community Guild Operators.
Koios is best described as a Decentralized and Elastic RESTful query layer for exploring data on Cardano blockchain to consume within applications/wallets/explorers/etc.
Resource and maintenance requirements for Cardano blockchain components (e.g. cardano-node, cardano-db-sync) are ever-growing. Along with that, every builder needs to identify how to query complex information from the chain.
