BlockDAG (BDAG) API Documentation

BlockDAG

BlockDAG (BDAG) is a blockchain network designed around a directed acyclic graph architecture, where multiple blocks can be produced and referenced in parallel instead of relying on a strictly linear chain structure. This model is intended to improve throughput, confirmation flow, and network scalability while preserving verifiable transaction ordering and node-based validation.

Through NOWNodes, developers can access BlockDAG infrastructure without running or maintaining their own node. The API provides a stable connection layer for reading blockchain data, submitting transactions, and integrating BlockDAG functionality into wallets, explorers, exchanges, monitoring tools, and Web3 applications.

BlockDAG API Methods and Endpoints

NOWNodes exposes BlockDAG's interface, depending on what your integration needs: RPC access for reading chain state, retrieving blocks and transactions, and broadcasting transactions to the network.

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