AnyRouter SDK

The official TypeScript SDK: one key and base URL for chat, embeddings, the Responses API, and the Anthropic Messages API, with typed requests, responses, errors, and automatic retries.

Quickstart

1. Install and set your key (from anyrouter.dev/dashboard/keys). The client reads ANYROUTER_API_KEY when you omit it:

   npm install @anyr/sdk
   export ANYROUTER_API_KEY=sk-ar-v1-...

2. Make a request:

   import { AnyRouter } from "@anyr/sdk"
   
   const client = new AnyRouter()
   
   const completion = await client.chat.completions.create({
     model: "z-ai/glm-4.7-flash",
     messages: [{ role: "user", content: "Hello!" }],
   })
   
   console.log(completion.choices[0].message.content)

Streaming

Pass stream: true:

const stream = await client.chat.completions.create({
  model: "z-ai/glm-4.7-flash",
  messages: [{ role: "user", content: "Write a haiku about TypeScript." }],
  stream: true,
})

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "")
}

Retries and timeouts

Transient failures (connection errors, timeouts, 429, 5xx) retry with exponential backoff that honors Retry-After. The timeout bounds the wait for the first response without aborting a running stream. Per call, pass signal (an AbortSignal), timeout, maxRetries, or headers:

const controller = new AbortController()

const stream = await client.chat.completions.create(
  { model: "z-ai/glm-4.7-flash", messages, stream: true },
  { signal: controller.signal, timeout: 30_000 },
)

Vercel AI SDK

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter() // reads ANYROUTER_API_KEY

const { text } = await generateText({
  model: anyrouter("z-ai/glm-4.7-flash"),
  prompt: "What is AnyRouter?",
})
