The @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Install the new package and update your imports — see client setup.

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

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

const result = await fal.subscribe("moonvalley/marey/pose-transfer", {
  input: {
    prompt: "Detailed Description: A venerable tribal chief, his weathered face marked with dark, ritualistic paint, stands proudly against a jungle backdrop. His elaborate headdress, a magnificent creation of numerous feathers, beads, and a central polished stone, sways gently with his movements. His initial stern expression softens into a confident smile as he begins to speak, his lips moving with unspoken words of wisdom or command. In a single, fluid motion, he raises his hand and gives a decisive wave, a gesture of both greeting and authority that underscores his leadership role within the tribe.

  Background: A dense tropical rainforest is blurred into a soft, verdant backdrop, with muted greens and browns suggesting a lush, humid environment.

  Middleground: The chief is the central focus, his head crowned by the large, intricate feathered headdress that moves subtly as he speaks. His shoulders and torso are visible, adorned with traditional necklaces.

  Foreground: His hand lifts into the frame, palm open, executing a single, confident wave toward the viewer before lowering again. The closest feathers of his headdress rustle with the motion.",
    video_url: "https://d1kaxrqq3vfrw5.cloudfront.net/fal-launch-assets/guide-assets/fal-pose-transfer-input.mp4"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In an environment where you cannot set environment variables, you can configure the API key manually on the client.

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

fal.config({
  credentials: "YOUR_FAL_KEY"
});

Protect your API Key

When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.

3. Queue#

Long-running requests

For long-running requests, such as training jobs or models with slower inference times, it is recommended to check the Queue status and rely on Webhooks instead of blocking while waiting for the result.

Submit a request#

The client API provides a convenient way to submit requests to the model.

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

const { request_id } = await fal.queue.submit("moonvalley/marey/pose-transfer", {
  input: {
    prompt: "Detailed Description: A venerable tribal chief, his weathered face marked with dark, ritualistic paint, stands proudly against a jungle backdrop. His elaborate headdress, a magnificent creation of numerous feathers, beads, and a central polished stone, sways gently with his movements.

    video_url: "https://d1kaxrqq3vfrw5.cloudfront.net/fal-launch-assets/guide-assets/fal-pose-transfer-input.mp4"
  },
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

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

const status = await fal.queue.status("moonvalley/marey/pose-transfer", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

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

const result = await fal.queue.result("moonvalley/marey/pose-transfer", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

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

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Auto uploads

The client will auto-upload the file for you if you pass a binary object (e.g. File, Data).

Read more about file handling in our file upload guide.
