@ultra-dex/sdk

Route AI calls across providers. Cut costs 30–50%. Automatic failover.

What is it?

@ultra-dex/sdk is an open-source TypeScript SDK that sits between your app and AI providers. It intelligently routes each request based on cost, latency, or your custom rules — with built-in circuit breakers, middleware, and cost tracking.

Install

npm install @ultra-dex/sdk

5-line quickstart

import { UltraDex } from '@ultra-dex/sdk'

const dex = new UltraDex()
dex.enableRouter({ strategy: 'cheapest' })

const response = await dex.chat([{ role: 'user', content: 'Hello' }])
// → Automatically routed to the cheapest available provider
