# Unified API (OpenAI compat)

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://e8aee267.previews.developers.cloudflare.com/ai-gateway/usage/chat-completion/index.md)|[Agent setup](https://e8aee267.previews.developers.cloudflare.com/agent-setup/)

Deprecated for single-model calls

For standard single-model chat completions, this endpoint is deprecated. Use the [REST API](https://e8aee267.previews.developers.cloudflare.com/ai-gateway/usage/rest-api/) instead, which provides OpenAI-compatible endpoints at `api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai/v1/chat/completions`. The `/compat/chat/completions` endpoint will continue to work for existing integrations.

Required for dynamic routing

[Dynamic routes](https://e8aee267.previews.developers.cloudflare.com/ai-gateway/features/dynamic-routing/) (`dynamic/{route}`) are invoked through this `/compat/chat/completions` endpoint. The REST API does not currently cover dynamic routing, so continue to use this endpoint when calling a dynamic route. See [Using a dynamic route](https://e8aee267.previews.developers.cloudflare.com/ai-gateway/features/dynamic-routing/usage/) for examples.

Cloudflare's AI Gateway offers an OpenAI-compatible `/chat/completions` endpoint, enabling integration with multiple AI providers using a single URL. This feature simplifies the integration process, allowing for seamless switching between different models without significant code modifications.

## Endpoint URL

```txt
https://gateway.ai.cloudflare.com/v1/{account_id}/default/compat/chat/completions
```

Replace `{account_id}` with your Cloudflare account ID. The `default` gateway is created automatically on your first request — no setup needed. You can also replace `default` with a specific gateway ID if you have already created one.

## Parameters

Switch providers by changing the `model` and `apiKey` parameters.

Specify the model using `{provider}/{model}` format. For example:

* `openai/gpt-5-mini`
* `google-ai-studio/gemini-2.5-flash`
* `anthropic/claude-sonnet-4-5`

## Examples

Make a request to 

![]() OpenAI

using 

OpenAI JS SDK
