# Proxy Provider Request

> Proxy a native provider request through ARouter using your ARouter API key.

ARouter's provider proxy forwards requests directly to a supported provider's native API while handling provider authentication for you.

<RequestExample>
  ```bash cURL theme={null}
  curl https://api.arouter.ai/openai/v1/chat/completions \
    -H "Authorization: Bearer lr_live_xxxx" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "gpt-5.4",
      "messages": [{"role": "user", "content": "Hello!"}]
    }'
  ```

  ```python Python theme={null}
  import requests

  resp = requests.post(
      "https://api.arouter.ai/anthropic/v1/messages",
      headers={
          "Authorization": "Bearer lr_live_xxxx",
          "Content-Type": "application/json",
      },
      json={
          "model": "claude-sonnet-4.6",
          "max_tokens": 1024,
          "messages": [{"role": "user", "content": "Hello!"}],
      },
  )
  print(resp.json())
  ```

  ```typescript Node.js theme={null}
  const response = await fetch("https://api.arouter.ai/google/v1beta/models/gemini-2.5-flash:generateContent", {
    method: "POST",
    headers: {
      Authorization: "Bearer lr_live_xxxx",
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      contents: [
        { role: "user", parts: [{ text: "Hello!" }] }
      ],
    }),
  });

  console.log(await response.json());
  ```
</RequestExample>

## Path Parameters

| Parameter  | Description                                                                  |
| ---------- | ---------------------------------------------------------------------------- |
| `provider` | Provider slug such as `openai`, `anthropic`, `google`, `deepseek`, or `groq` |
| `path`     | Native API path to forward after the provider prefix                         |

## Notes

* Requests and responses are passed through in the provider's native format.
* ARouter injects the provider credential automatically. You only send your ARouter API key.
* Usage is still metered against your ARouter account.
* Use this endpoint when you need provider-native features that are not represented in the normalized ARouter request schema.
