Endpoint: POST /generation/text-to-model
Generate a 3D model from a text prompt using P Series. Optimized for low-poly output with clean topology.
Note
- This endpoint requires an API Key. Include it in the Authorization header as Bearer {api_key}.
- This is an asynchronous API. After submitting the request, use the Task Query API to poll for results, or configure a Webhook to receive automatic notifications when the task completes.
Request Parameters
Request Body
promptstringRequired
Text prompt, up to 1024 characters. Describe shape, material, style, and scale.
Notes
- Good: "A low-poly medieval wooden treasure chest with iron hinges and a rusty lock."
- Bad: "A box."
- Include material and style hints for better PBR results.
negative_promptstring
Negative prompt, up to 255 characters. Describe what you do NOT want in the generated model. For example: "blurry, low quality, broken mesh".
image_seedinteger
Random seed for the internal text-to-image stage. Controls the reference image generated from your text prompt before 3D conversion. If not set, a random seed is used each time.
modelstringRequired
P Series model version.
P1-20260311— optimized for low-poly generation.
model_seedinteger
Random seed for geometry generation. Using the same seed with the same input will produce an identical 3D mesh. If not set, a random seed is used each time.
face_limitinteger
Maximum polycount for the output mesh.
Notes
- Supported range: 50 – 20,000
- If omitted, adaptively determined.
For best quality: simple models start from 150 faces, complex models start from 250 faces. Lower values may result in poor generation quality.
texturebooleandefault: true
Whether to generate texture maps for the model. Set to false to get a bare geometry without any textures. Default is true.
pbrbooleandefault: true
Enable PBR material maps (
base_color, metallic, roughness, normal).When
pbr is set to true, texture will be automatically forced to true.texture_seedinteger
Random seed for texture generation. Using the same seed will produce identical textures. If not set, a random seed will be used each time. To get a model with different textures but the same geometry, keep model_seed unchanged and vary texture_seed.
texture_qualitystringdefault: standard
Texture quality level.
standard— balanced quality and speed.detailed— higher fidelity, slower generation.extreme— 8K textures, highest fidelity. Costs additional credits compared to detailed.
auto_sizebooleandefault: false
Whether to automatically scale the generated model to real-world dimensions. When enabled, the model size will be in meters, suitable for AR/VR or game engine scenes. Default is false.
compressstring
Compression type.
geometry— meshopt compression for reduced file size.
Notes
- The following parameters are only valid when
model ≥ v3.0-20250812:texture_quality,geometry_quality,auto_size,quad,smart_low_poly,generate_parts,compress.
export_uvbooleandefault: true
Controls UV unwrapping. Set
false for faster generation and smaller file size.Examples
