Koios Python

Overview

Koios Python is Python wrapper which allow interacting with all information and parameters stored on the Cardano blockchain using Koios REST API

What is Koios Python?

Koios Python is a library 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.

Koios is really useful for developers because resource and maintenance requirements for Cardano blockchain components (e.g. cardano-node, cardano-db-sync) are ever-growing. It also simplifies how to query complex information from the blockchain.

This library allows getting data from the Cardano Blockchain using a simple syntaxis in your Python code. All the querys follow Koios API REST operations.
