# OpenRouter

[OpenRouter ↗](https://openrouter.ai/) is a platform that provides a unified interface for accessing and using large language models (LLMs).

## Endpoint

```
https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/openrouter
```

## URL structure

When making requests to [OpenRouter ↗](https://openrouter.ai/), replace `https://openrouter.ai/api/v1/chat/completions` in the URL you are currently using with `https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/openrouter/chat/completions`.

## Prerequisites

When making requests to OpenRouter, ensure you have the following:

* Your AI Gateway Account ID.
* Your AI Gateway gateway name.
* An active OpenRouter API token or a token from the original model provider.
* The name of the OpenRouter model you want to use.

## Examples

### cURL

Request

```
curl -X POST https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/openrouter/v1/chat/completions \ --header 'content-type: application/json' \ --header 'Authorization: Bearer OPENROUTER_TOKEN' \ --data '{    "model": "openai/gpt-5-mini",    "messages": [        {            "role": "user",            "content": "What is Cloudflare?"        }    ]}'
```

### Use OpenAI SDK with JavaScript

If you are using the OpenAI SDK with JavaScript, you can set your endpoint like this:

JavaScript

```
import OpenAI from "openai";
const openai = new OpenAI({  apiKey: env.OPENROUTER_TOKEN,  baseURL:    "https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY/openrouter",});
try {  const chatCompletion = await openai.chat.completions.create({    model: "openai/gpt-5-mini",    messages: [{ role: "user", content: "What is Cloudflare?" }],  });
  const response = chatCompletion.choices[0].message;
  return new Response(JSON.stringify(response));} catch (e) {  return new Response(e);}
```
