Tripo3D H3.1 API

Tripo3D H3.1 supports high-detail text-to-3D, single image-to-3D, and multiview-to-3D generation through three public model IDs.

Available Models

  • tripo3d-h3.1-text-to-3d - Generate a high-detail 3D model from a prompt
  • tripo3d-h3.1-image-to-3d - Generate a 3D model from one object image
  • tripo3d-h3.1-multiview-to-3d - Generate a 3D model from 2-4 views of the same object

Required Parameters

  • model: tripo3d-h3.1-text-to-3d, tripo3d-h3.1-image-to-3d, or tripo3d-h3.1-multiview-to-3d
  • input.prompt: Required for tripo3d-h3.1-text-to-3d
  • input.image_urls: Required for image models. Use exactly one item for image-to-3D; use 2-4 items for multiview-to-3D

Optional Parameters

  • negative_prompt: Text-to-3D only. Features to avoid
  • face_limit: Target face count, from 1000 to 2000000
  • texture: Whether to generate textures. Default is true
  • pbr: Whether to generate PBR materials when textures are enabled
  • model_seed, image_seed, texture_seed: Optional integer seeds
  • texture_quality: standard or detailed. Default is standard
  • geometry_quality: standard or detailed. Default is standard
  • auto_size: Whether to auto-scale the model
  • quad: Whether to generate quad mesh topology
  • callback_url: Optional webhook URL for task completion notification

Pricing

  • Text-to-3D and multiview-to-3D: 15 credits without textures, 30 credits with standard textures, or 45 credits with detailed textures
  • Image-to-3D: 30 credits without textures, 45 credits with standard textures, or 60 credits with detailed textures
  • Detailed geometry adds 30 credits
  • Quad mesh adds 7.5 credits

Output

The task result is returned as a file list. Available items may include:
  • model_glb
  • thumbnail
  • entries from model_urls, such as glb, base_model, and pbr_model, when available
Each file item includes label, file_url, file_type, format, content_type, file_name, and file_size when available.

Notes

  • Multiview inputs should show the same object from different angles.
  • The API returns asynchronous task status. Poll the unified task status endpoint or use callback_url.
