# OpenRouter

> Connect OpenRouter as an AI Gateway provider

An OpenRouter provider forwards Chat Completions requests to OpenRouter. Use it as an aggregator when you want one key to reach many upstream models through OpenAI Chat Completions.

See [AI Providers](/manage/ai/providers/overview) if you haven't created a provider before. Field options are in [Provider Configuration](/manage/ai/providers/configuration).

## Defaults

| Setting      | Value                          |
| ------------ | ------------------------------ |
| Upstream URL | `https://openrouter.ai/api/v1` |
| Auth type    | Bearer                         |
| Capabilities | OpenAI Chat Completions        |

OpenRouter's default capability is Chat Completions only. Clients that require Responses or Anthropic Messages need a different provider, extra capabilities this OpenRouter account actually supports, or a [custom](/manage/ai/providers/custom) endpoint.

## Configure

1. Sidebar → **AI Gateway** → **Providers** → **Create**.
2. Set **Provider Type** to **OpenRouter**. Name, capabilities, upstream URL, and auth type fill in from the defaults above.
3. Paste your OpenRouter API key.
4. Set **Allow** and **Block** lists. OpenRouter model keys are often vendor-prefixed, for example `openai/gpt-4o` or `anthropic/claude-sonnet-4`.
5. Save, then attach the provider to an [AI Gateway resource](/manage/ai/overview).

## Models

OpenRouter is an aggregator. See [Model Routing](/manage/ai/providers/model-routing) for how allow lists and `GET /v1/models` discovery work. Add exact keys such as `openai/gpt-4o` or `anthropic/claude-sonnet-4`.
