Avalanche (AVAX)

Avalanche (AVAX) Documentation with NOWNodes

The Avalanche API provides a unified way to interact with the Avalanche network, including the P-Chain, X-Chain, and C-Chain. These interfaces enable developers to query blocks, manage subnets, access AVAX balances, submit transactions, and interact with EVM-compatible smart contracts. This doc gives an overview for those searching for Avalanche docs, api docs, submit transaction, and integration into web environments. Through NOWNodes, developers can access Avalanche Mainnet infrastructure without deploying or maintaining their own nodes. The service ensures a stable, scalable, and secure connection to the network, ideal for integrating blockchain functionality into code, applications, and web services at production level.

NOWNodes Avalanche (AVAX) Interfaces

  • Avalanche P-Chain API – Provides access to subnet management, validators, staking operations, and platform-level metadata on the P-Chain.

  • Avalanche X-Chain API – Supports asset transfers, UTXO operations, and blockchain queries for the Avalanche Exchange Chain.

  • Avalanche C-Chain API – EVM-compatible interface enabling smart contract calls, balances, gas estimation, and transaction submission.

  • Avalanche Health Endpoint – Returns node and network health status for monitoring and automated infrastructure checks.

  • Avalanche Index API – Offers fast indexed access to transactions, addresses, and historical datasets for analytics and application backends.

  • Avalanche WebSocket (WSS) – Provides live event streaming, mempool updates, block notifications, and real-time transaction tracking.

  • Avalanche BlockBook API – UTXO-style blockchain explorer interface delivering balance, transaction, and block queries.

  • Avalanche BlockBook WSS – Real-time streaming interface for BlockBook data including instant updates for wallets and monitoring tools.

Using the Avalanche API docs with NOWNodes, developers can efficiently integrate AVAX functionality into any application, leveraging multiple chain interfaces depending on their architectural requirements. The documentation ensures consistent support for building reliable infrastructure, enabling seamless implementation into your code and backend services with high availability and industry-level performance.
