@axonsdk/sdk

Provider-abstracted SDK for deploying and calling confidential edge applications across DePIN compute networks.

Overview

@axonsdk/sdk is the core library for the Axon platform. It gives you a single, unified interface to deploy code and exchange messages with processors running on any supported DePIN network — without changing your application logic when you switch providers.

Supported providers: Acurast · Akash Network · Fluence · Koii

Installation

npm install @axonsdk/sdk

Requires Node.js ≥ 20.

Quick start

import { AxonClient } from '@axonsdk/sdk';

const client = new AxonClient({
  provider: 'akash',            // 'acurast' | 'fluence' | 'koii' | 'akash'
  secretKey: process.env.AXON_SECRET_KEY,
});

await client.connect();

const deployment = await client.deploy({
  runtime: 'nodejs',
  code: './dist/index.js',
  schedule: { type: 'on-demand', durationMs: 86_400_000 },
  replicas: 1,
});

await client.send(deployment.processorIds[0], { prompt: 'Hello' });

client.onMessage((msg) => console.log(msg.payload));

client.disconnect();

Multi-provider Router

Route across multiple providers simultaneously with automatic failover, circuit breaking, and health-based scoring:

import { AxonRouter } from '@axonsdk/sdk';

const router = new AxonRouter({
  providers: ['akash', 'acurast'],
  secretKey: process.env.AXON_SECRET_KEY,
  strategy: 'latency',          // 'balanced' | 'latency' | 'availability' | 'cost' | 'round-robin'
  processorStrategy: 'fastest', // 'round-robin' | 'fastest' | 'random' | 'first'
  failureThreshold: 3,
  recoveryTimeoutMs: 30_000,
  maxRetries: 2,
});

await router.connect();
await router.deploy(config);     // deploys to ALL providers in parallel

await router.send({ prompt: 'Hello' }); // auto-picks the best provider

router.health().forEach((h) => {
  console.log(h.provider, h.latencyMs, h.circuitState, h.score);
});

Routing strategies

Strategy	Best for
`balanced`	General purpose — equal weight on availability, latency, cost
`latency`	Interactive workloads — always picks the fastest provider
`availability`	High uptime — prefers the most reliable provider
`cost`	Batch jobs — routes to the cheapest option
`round-robin`	Even load distribution

Mobile (iOS & Android)

Use @axonsdk/mobile for React Native / Expo apps.

CLI

npm install -g @axonsdk/cli
axon init
axon deploy
