Request Attribution

ARouter supports optional HTTP headers that identify your application in API requests. These headers are used for source tracking inside ARouter Dashboard analytics and activity views, helping you understand which apps or workflows are driving your API usage.

Headers

`HTTP-Referer`

Your application’s URL. Used to identify the source of the request.

HTTP-Referer: https://myapp.com

`X-Title`

Your application’s display name. Shows up in your Dashboard activity view.

X-Title: My AI App

Implementation

Include these headers in any request to the ARouter API:

Python (OpenAI)
Node.js (OpenAI)
Go
cURL
fetch

from openai import OpenAI

client = OpenAI(
    base_url="https://api.arouter.ai/v1",
    api_key="lr_live_xxxx",
    default_headers={
        "HTTP-Referer": "https://myapp.com",
        "X-Title": "My AI App",
    },
)

response = client.chat.completions.create(
    model="openai/gpt-5.4",
    messages=[{"role": "user", "content": "Hello!"}],
)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.arouter.ai/v1",
  apiKey: "lr_live_xxxx",
  defaultHeaders: {
    "HTTP-Referer": "https://myapp.com",
    "X-Title": "My AI App",
  },
});

const response = await client.chat.completions.create({
  model: "openai/gpt-5.4",
  messages: [{ role: "user", content: "Hello!" }],
});

client := arouter.NewClient("lr_live_xxxx",
    arouter.WithBaseURL("https://api.arouter.ai/v1"),
    arouter.WithHeader("HTTP-Referer", "https://myapp.com"),
    arouter.WithHeader("X-Title", "My AI App"),
)

curl https://api.arouter.ai/v1/chat/completions \
  -H "Authorization: Bearer lr_live_xxxx" \
  -H "HTTP-Referer: https://myapp.com" \
  -H "X-Title: My AI App" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-5.4",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

const response = await fetch('https://api.arouter.ai/v1/chat/completions', {
  method: 'POST',
  headers: {
    Authorization: 'Bearer lr_live_xxxx',
    'HTTP-Referer': 'https://myapp.com',
    'X-Title': 'My AI App',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'openai/gpt-5.4',
    messages: [{ role: 'user', content: 'Hello!' }],
  }),
});

Dashboard Activity

When you include these headers, your Dashboard activity view displays:

Referer: The source URL or app name associated with each request
Title: Your app’s display name for easy identification

This is especially useful when managing multiple applications or workflows under a single ARouter account. These headers are only used for ARouter-side analytics and attribution. They do not change model behavior or routing.
