About

Generate a 3D model from text using Meshy-6 Preview.

Supports two modes:

preview: Returns untextured geometry only (20 credits)
full: Returns fully textured model (30 credits + optional texture guidance)

Meshy-6 Preview features:

Latest model with best quality
Most accurate text understanding
Superior geometry and texture quality
Best for high-quality creative results

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. Please check the migration guide for more information.

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/meshy/v6-preview/text-to-3d", {
  input: {
    prompt: "A rustic, antique wooden treasure chest with a curved, domed lid, constructed from weathered, dark brown planks exhibiting prominent wood grain and subtle distress. It's heavily reinforced with broad, dark grey, oxidized metal bands secured by numerous circular rivets. Ornate, dark iron decorative elements featuring swirling foliate patterns and dragon motifs adorn the corners and lid. A prominent, circular, intricately carved metal lock plate with a central keyhole dominates the front, flanked by two large, dark metallic pull rings."
  },
  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 case your app is running in an environment where you cannot set environment variables, you can set the API Key manually as a client configuration.

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/meshy/v6-preview/text-to-3d", {
  input: {
    prompt: "A rustic, antique wooden treasure chest with a curved, domed lid, constructed from weathered, dark brown planks exhibiting prominent wood grain and subtle distress. It's heavily reinforced with broad, dark grey, oxidized metal bands secured by numerous circular rivets. Ornate, dark iron decorative elements featuring swirling foliate patterns and dragon motifs adorn the corners and lid. A prominent, circular, intricately carved metal lock plate with a central keyhole dominates the front, flanked by two large, dark metallic pull rings."
  },
  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/meshy/v6-preview/text-to-3d", {
  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/meshy/v6-preview/text-to-3d", {
  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

Describe what kind of object the 3D model is. Maximum 600 characters.

mode ModeEnum

Generation mode. 'preview' returns untextured geometry only, 'full' returns textured model (preview + refine). Default value: "full"

Possible enum values: preview, full

art_style ArtStyleEnum

Desired art style of the object. Note: enable_pbr should be false for sculpture style. Default value: "realistic"

Possible enum values: realistic, sculpture

seed integer

Seed for reproducible results. Same prompt and seed usually generate the same result.

topology TopologyEnum

Specify the topology of the generated model. Quad for smooth surfaces, Triangle for detailed geometry. Default value: "triangle"

Possible enum values: quad, triangle

target_polycount integer

Target number of polygons in the generated model Default value: 30000

should_remesh boolean

Whether to enable the remesh phase. When false, returns unprocessed triangular mesh. Default value: true

symmetry_mode SymmetryModeEnum

Controls symmetry behavior during model generation. Default value: "auto"

Possible enum values: off, auto, on

is_a_t_pose boolean

Whether to generate the model in an A/T pose

enable_pbr boolean

Generate PBR Maps (metallic, roughness, normal) in addition to base color. Should be false for sculpture style.

enable_prompt_expansion boolean

Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.

texture_prompt string

Additional text prompt to guide the texturing process (only used in 'full' mode)

texture_image_url string

2D image to guide the texturing process (only used in 'full' mode)

enable_safety_checker boolean

If set to true, input data will be checked for safety before processing. Default value: true
