# Fal AI

[Fal AI ↗](https://fal.ai/) provides access to 600+ production-ready generative media models through a single, unified API. The service offers the world's largest collection of open image, video, voice, and audio generation models, all accessible with one line of code.

## Endpoint

```

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


```

## URL structure

When making requests to Fal AI, replace `https://fal.run` in the URL you're currently using with `https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/fal`.

## Prerequisites

When making requests to Fal AI, ensure you have the following:

* Your AI Gateway Account ID.
* Your AI Gateway gateway name.
* An active Fal AI API token.
* The name of the Fal AI model you want to use.

## Default synchronous API

By default, requests to the Fal AI endpoint will hit the synchronous API at `https://fal.run/<path>`.

### cURL example

Terminal window

```

curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/fal/fal-ai/fast-sdxl \

  --header 'Authorization: Key {fal_ai_token}' \

  --header 'Content-Type: application/json' \

  --data '{

    "prompt": "Make an image of a cat flying an aeroplane"

  }'


```

## Custom target URLs

If you need to hit a different target URL, you can supply the entire Fal target URL in the `x-fal-target-url` header.

### cURL example with custom target URL

Terminal window

```

curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/fal \

  --header 'Authorization: Bearer {fal_ai_token}' \

  --header 'x-fal-target-url: https://queue.fal.run/fal-ai/bytedance/seedream/v4/edit' \

  --header 'Content-Type: application/json' \

  --data '{

    "prompt": "Dress the model in the clothes and hat. Add a cat to the scene and change the background to a Victorian era building.",

    "image_urls": [

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_1.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_2.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_3.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_4.png"

    ]

  }'


```

## WebSocket API

Fal AI also supports real-time interactions through WebSockets. For WebSocket connections and examples, see the [Realtime WebSockets API documentation](https://developers.cloudflare.com/ai-gateway/usage/websockets-api/realtime-api/#fal-ai).

## JavaScript SDK integration

The `x-fal-target-url` format is compliant with the Fal SDKs, so AI Gateway can be easily passed as a `proxyUrl` in the SDKs.

### JavaScript SDK example

JavaScript

```

import { fal } from "@fal-ai/client";


fal.config({

  credentials: "{fal_ai_token}", // OR pass a cloudflare api token if using BYOK on AI Gateway

  proxyUrl: "https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/fal"

});


const result = await fal.subscribe("fal-ai/bytedance/seedream/v4/edit", {

  "input": {

    "prompt": "Dress the model in the clothes and hat. Add a cat to the scene and change the background to a Victorian era building.",

    "image_urls": [

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_1.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_2.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_3.png",

      "https://storage.googleapis.com/falserverless/example_inputs/seedream4_edit_input_4.png"

    ]

  }

});


console.log(result.data.images[0]);
