Radix (XRD) API Documentation

Radix

Radix (XRD) is a proof-of-stake Layer 1 using Cerberus consensus, with the Babylon mainnet introducing the Radix Engine and Scrypto-based smart contract model. Components and blueprints are written in Scrypto and execute through the Radix Engine against an entity-oriented state model, while full nodes validate transactions and maintain substates, components, resources, accounts, and ledger history. This resource-oriented model differs from both EVM accounts and Bitcoin UTXOs, making entities, resources, manifests, and substates the principal primitives exposed to applications.

Radix API Methods and Endpoints

NOWNodes exposes Radix's interface, plus a few others, depending on what your integration needs: its native Core API for node and ledger-state operations, and Gateway API for indexed account, transaction, entity, and ledger lookups. Archive mode extends these interfaces to historical states and data beyond standard retention.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
