+pcx_content_type: get-started
+---
+
+[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
+
+```txt
+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
+
+```bash
+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
+
+```bash
+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](/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
+
+```js
+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]);
+```
