Quickstart

AnyRouter is a drop-in replacement for the OpenAI API. Point base_url at AnyRouter, pass your key, and use a provider/model id — no other code changes.

from openai import OpenAI

client = OpenAI(
    base_url="https://anyrouter.dev/api/v1",
    api_key="sk-ar-v1-your-key",
)

response = client.chat.completions.create(
    model="z-ai/glm-4.7-flash",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

import OpenAI from "openai"

const client = new OpenAI({
  baseURL: "https://anyrouter.dev/api/v1",
  apiKey: "sk-ar-v1-your-key",
})

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

Install @anyr/sdk and call chat.completions.create. The client reads ANYROUTER_API_KEY when you omit the key, and targets https://anyrouter.dev/api/v1 by default. Attribution headers are sent automatically so usage shows up in rankings and analytics.

npm install @anyr/sdk

export ANYROUTER_API_KEY="sk-ar-v1-your-key"

import { AnyRouter } from "@anyr/sdk"

// Reads the key from ANYROUTER_API_KEY when omitted.
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)

See the SDK guide and Chat Completions API reference for the full request and response shape.

Any OpenAI-compatible framework — the Vercel AI SDK, LangChain, LlamaIndex — works the same way: set the base URL, supply your key, and reference models by their provider/model id.

import { createOpenAI } from "@ai-sdk/openai"

const anyrouter = createOpenAI({
  baseURL: "https://anyrouter.dev/api/v1",
  apiKey: process.env.ANYROUTER_API_KEY,
})

const model = anyrouter("anthropic/claude-sonnet-4.6")
