AvalancheGo APIs

Clients interact with Avalanche through APIs calls to nodes. Numeric parameters in API calls may be given as strings (e.g., "5" or 5 are both ok for an integer argument). Numeric return values are always given as strings (e.g., "5" rather than 5). In examples, API calls are made to a node listening for HTTP traffic on 127.0.0.1:9650.

Issuing API Calls

This guide explains how to make calls to APIs exposed by Avalanche nodes.

The Platform Chain (P-Chain) API

Allows clients to interact with the P-Chain (Platform Chain), which maintains Avalanche’s validator set and handles blockchain and subnet creation.

The Contract Chain (C-Chain) API

Allows clients to interact with the C-Chain, Avalanche’s main EVM instance, as well as other EVM instances.

The Exchange Chain (X-Chain) API

Allows clients to create and trade assets, including AVAX, on the X-Chain as well as other instances of the AVM.

The Admin API

Allows clients to examine a node’s internal state, set of connections, and similar internal protocol data.

The Auth API

Allows clients to manage the creation and revocation of authorization tokens.

The Health API

Allows clients to check a node’s health.

The Info API

Allows clients to examine basic information about a node.

The IPC API

Allows users to create UNIX domain sockets for blockchains to publish to.

The Keystore API

Allows customers to use the embedded Keystore file of an Avalanche node.

The Metrics API

Allows clients to get statistics about a node’s health and performance.
