1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Migrate to @fal-ai/client

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("fal-ai/glm-image", {
  input: {
    prompt: "An elegant close-up photograph of hands holding a beautifully illustrated watercolor menu card. The hands have natural sun-kissed skin with a delicate gold ring, gripping the menu gently and refined.

  The menu is a work of art—hand-painted watercolor illustration on textured cream watercolor paper with soft deckled edges:

  - Top: \"AZURE\" painted in flowing navy blue watercolor calligraphy with organic brushstroke texture and slight color bleeding
  - Watercolor illustration border: delicate tropical elements painted in soft washes—translucent turquoise waves flowing along the edges, loose coral and pink hibiscus flowers in the corners, gentle green palm leaf strokes, and small golden paint splatters suggesting sunlight
  - Center menu items in elegant hand-lettered watercolor script with slight variations in ink density:

    \"Tuna Tartare — 24\"
    \"Sea Bass — 32\"
    \"Mango Pavlova — 14\"

  - Bottom: \"Koh Samui\" in small watercolor lettering with a tiny painted wave

  The watercolor has beautiful organic qualities—soft color gradients, natural paper texture visible through transparent washes, slight bleeding at edges of brushstrokes, layered translucent blues and greens creating depth. The paint has a luminous, fresh quality with white paper showing through in places.

  Background: dreamy out-of-focus turquoise ocean with sparkling bokeh lights reflecting off water, creating soft circular light spots in aqua and gold tones. The blurred background complements the watercolor aesthetic perfectly.

  Lighting: warm natural golden hour sunlight from upper left, illuminating the watercolor pigments and making them glow. The light catches the textured watercolor paper beautifully, showing subtle shadows in the paint layers and paper grain.

  Photography style: shot on 85mm f/1.4, shallow depth of field with only the menu in sharp focus. High-end editorial aesthetic that celebrates the handmade, artistic quality of the watercolor. Color palette: cream paper, translucent turquoise and teal watercolors, soft coral pink, navy blue, gentle greens, golden accents, warm skin tones.

  The overall mood is artistic, luxurious, handcrafted—like a boutique resort that values artistry and craftsmanship. The watercolor style feels fresh, organic, and elevated."
  },
  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("fal-ai/glm-image", {
  input: {
    prompt: "An elegant close-up photograph of hands holding a beautifully illustrated watercolor menu card. The hands have natural sun-kissed skin with a delicate gold ring, gripping the menu gently and refined.

  The menu is a work of art—hand-painted watercolor illustration on textured cream watercolor paper with soft deckled edges:

  },
  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("fal-ai/glm-image", {
  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("fal-ai/glm-image", {
  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.

5. Schema#

Input#

prompt string* required

Text prompt for image generation.

image_size ImageSize | Enum

Output image size. Default value: square_hd

Possible enum values: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9, portrait_3_2, landscape_3_2, portrait_hd, landscape_hd

Note: For custom image sizes, you can pass the width and height as an object:

"image_size": {
  "width": 1280,
  "height": 720
}

num_inference_steps integer

Number of diffusion denoising steps. More steps generally produce higher quality images. Default value: 30

seed integer

Random seed for reproducibility. The same seed with the same prompt will produce the same image.

num_images integer

Number of images to generate. Default value: 1

enable_safety_checker boolean

Enable NSFW safety checking on the generated images. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images. Default value: true

output_format OutputFormatEnum

Output image format. Default value: "jpeg"

Possible enum values: jpeg, png

sync_mode boolean

If True, the image will be returned as a base64 data URI instead of a URL.

enable_prompt_expansion boolean

If True, the prompt will be enhanced using an LLM for more detailed and higher quality results.
