Text To 3D API is a feature that allows you to integrate Meshy's Text to 3D capabilities into your own application. In this section, you'll find all the information
you need to get started with this API.
This endpoint allows you to create a new Text to 3D Preview task. Refer to
The Text to 3D Task Object to see which
properties are included with Text to 3D task object.
Parameters
Required attributes
Name
mode
Type
string
Description
This field should be set to "preview" when creating a preview task.
Name
prompt
Type
string
Description
Describe what kind of object the 3D model is.
Optional attributes
Name
negative_prompt
Type
string
Description
Describe what the model should not look like.
Name
art_style
Type
string
Description
Describe your desired art style of the object.
Default to realistic if not specified. Available values:
realistic: Realistic style
cartoon: Cartoon style
low-poly: Low Poly style
sculpture: Sculpture style
pbr: PBR style
When you are using meshy-4 ai_model, only realistic, sculpture and pbr are available.
Name
seed
Type
integer
Description
When you use the same prompt and seed, you will generate the same result.
Name
ai_model
Type
string
Description
ID of the model to use.
Default to meshy-4 if not specified. Available values:
meshy-4
meshy-3-turbo
meshy-3
The refine task will use the same model as the corresponding preview task.
Name
topology
Type
string
Description
Specify the topology of the generated model.
Default to triangle if not specified. Available values:
quad: Generate a quad-dominant mesh.
triangle: Generate a decimated triangle mesh.
This parameter is effective only if ai_model is set to meshy-4.
Name
target_polycount
Type
integer
Description
Specify the target number of polygons in the generated model. The actual number of polygons may deviate from the target depending on the complexity of the geometry.
The valid value range varies depending on the user tier:
Premium users: 3,000 to 100,000 (inclusive)
Free users: 10,000 to 30,000 (inclusive)
Default to 30,000 if not specified.
This parameter is effective only if ai_model is set to meshy-4.
Name
should_remesh
Type
boolean
Description
The should_remesh flag controls whether to enable the remesh phase.
When set to false, it directly returns a triangular mesh, ignoring topology and target_polycount.
Default to true if not specified.
This parameter is effective only if ai_model is set to meshy-4.
Returns
The result property of the response contains the task id of the newly created Text to 3D task.
This endpoint allows you to retrieve a Text to 3D task given a valid task id.
Refer to The Text to 3D Task Object to see which
properties are included with Text to 3D task object.
Parameters
Name
id
Type
path
Description
Unique identifier for the Text to 3D task to retrieve.
The Text to 3D Task object is a work unit that Meshy keeps track of to generate a 3D model from a text input. There are two stages of the Text to 3D API, preview and refine. Preview stage is for generating a mesh-only 3D model, and refine stage is for generating a textured 3D model based on the preview stage's result.
The object has the following properties:
Properties
Name
id
Type
string
Description
Unique identifier for the task. While we use a k-sortable UUID for task ids as the
implementation detail, you should not make any assumptions about the format of the id.
Name
model_urls
Type
object
Description
Downloadable URL to the textured 3D model file generated by Meshy.
Name
glb
Type
string
Description
Downloadable URL to the GLB file.
Name
fbx
Type
string
Description
Downloadable URL to the FBX file.
Name
usdz
Type
string
Description
Downloadable URL to the USDZ file.
Name
obj
Type
string
Description
Downloadable URL to the OBJ file.
Name
mtl
Type
string
Description
Downloadable URL to the MTL file.
Name
prompt
Type
string
Description
This is unmodified prompt that was used to create the task.
Name
negative_prompt
Type
string
Description
This is unmodified negative_prompt that was used to create the task.
Name
art_style
Type
string
Description
This is unmodified art_style that was used to create the preview task.
Name
texture_richness
Type
string
Description
This is unmodified texture_richness that was used to create the refine task. If the task is created with ai_model: "meshy-4", there is no texture_richness property.
Name
thumbnail_url
Type
string
Description
Downloadable URL to the thumbnail image of the model file.
Name
video_url
Type
string
Description
Downloadable URL to the preview video.
Name
progress
Type
integer
Description
Progress of the task. If the task is not started yet, this property will be 0. Once the task has succeeded, this will become 100.
Name
seed
Type
integer
Description
Seed of the task.
Name
started_at
Type
timestamp
Description
Timestamp of when the task was started, in miliseconds. If the task is not started yet, this property will be 0.
A timestamp represents the number of milliseconds elapsed since January 1, 1970 UTC, following
the RFC 3339 standard.
For example, Friday, September 1, 2023 12:00:00 PM GMT is represented as 1693569600000. This applies
to all timestamps in Meshy API.
Name
created_at
Type
timestamp
Description
Timestamp of when the task was created, in miliseconds.
Name

Name
texture_urls
Type
array
Description
An array of texture URL objects that are generated from the task. Normally this only contains one texture URL object. Each texture URL has the following properties:
If the task is created with art_style: "voxel", this property will be an empty list.
Name
base_color
Type
string
Description
Downloadable URL to the base color map image.
Name
preceding_tasks
Type
integer
Description
The count of preceding tasks.
The value of this field is meaningful only if the task status is PENDING.
