edit_model

Change a model you have: retexture (new PBR textures from a picture or words; trellis-2-texture 5, trellis-2-texture-pro 10, tripo-texture 20, tripo-texture-detailed 40 credits) or remesh (new, clean topology at a face count; tripo-remesh 50 credits). The mesh is an https URL, an upload id from upload_file, a library id (ph:wooden_barrel_01) or a job id, so steps chain without downloading. Waits about 45 s, then returns job_id for get_job. To reduce, compress, convert or repair a file, use gltf-transform or Blender locally.

Argument	Type	Description
mesh*	string	The model: URL, upl_..., library id, or job_...
image	string	retexture: the look as a picture.
model	string	retexture or remesh: the model to use.
prompt	string	retexture: the look in words, when there is no picture.
options	object	remesh: faces (500 to 20,000; 10,000 as quads), topology (quads\|triangles).
operation*	string
max_credits	integer
wait_seconds	integer
idempotency_key	string

generate_model

Make one 3D object (never a scene) as a textured GLB, from a picture (image) or a description (prompt). Costs credits, which the user bought: image models trellis-2 5, trellis-2-pro 15, hunyuan-3d-3-1-pro 90, tripo-3-1 50, tripo-3-1-detailed 100; from a prompt add the picture model (flux-2-klein 1). Pass max_credits to refuse anything dearer. For a game or the web pass max_faces (5000-20000; the default is 200,000 triangles), and from a prompt style lowpoly to match low-poly kits. The GLB stands on its base at the origin, like library models. Waits about 45 s, then returns job_id for get_job if it is not done. Calling again with the same arguments resumes the same job and never charges twice; pass a new idempotency_key to make another one.

Argument	Type	Description
seed	integer
image	string	A picture of one object: an https URL, a data: URI, an upload id from upload_file, or a job id.
model	string	Default trellis-2. See account for every model and its price.
style	string	From a prompt: lowpoly draws a flat-shaded, flat-colour game asset to match low-poly kits; stylized a hand-painted look.
prompt	string	A description of one object: "a weathered wooden barrel with iron bands".
max_faces	integer	Most triangles in the model, at no extra cost: 5,000-20,000 for game or web use (the default is 200,000).
image_model

generate_texture

A seamless PBR texture set (base colour, normal, height, roughness, metallic at 2048 px) from a description, for flux-2-klein-material 2, muse-image-material 5, gpt-image-2-5-material 8 credits.

Argument	Type	Description
seed	integer
model	string	Default flux-2-klein-material.
prompt*	string	The surface: "mossy cobblestones", "brushed steel".
max_credits	integer
wait_seconds	integer
idempotency_key	string

get_asset

Full details for one library asset: download URLs per format and resolution, size in metres, up axis and origin, texture maps, a credit line (credit, credit_html), related assets, and import notes for Godot, Unity, three.js and Blender. When you write credits or a README for a project using the asset, include its credit line. Read-only, free.

read-only

Argument	Type	Description
id*	string	An asset id from search_assets, e.g. "ph:wooden_barrel_01".

{
  "type": "object",
  "required": [
    "id"

      "description": "An asset id from search_assets, e.g. \"ph:wooden_barrel_01\"."
    }
  },
  "additionalProperties": false
}

get_job

Waits up to about 45 s for a job to finish, or reads where it stands. Safe to call again and again; never charges. When done: download URLs for every file, a preview picture, the model's size in metres and triangle count, and an asset id usable as input to the next step.

read-only

Argument	Type	Description
job_id*	string
wait_seconds	integer

  "type": "object",

      "maximum": 50,
      "minimum": 0
    }
  },
  "additionalProperties": false
}

search_assets

Search the free CC0 library of 3D models, PBR textures and HDRIs by meaning and filters. Every model is a GLB measured in metres, +Y up, origin at the base. Check size_m before placing an asset; use min_size_m >= 2 for floors and walls. previews (max 6) attaches thumbnails, which is cheaper than downloading the wrong asset. Each result has match (strong, good or weak); when none is better than weak the answer says so, and generate_model is the way to get the object. Read-only, free with a free account.

read-only

Argument	Type	Description
q	string	What you need, in words: "wooden barrel", "mossy rock", "sci-fi crate".
maps	array	Must have all of these maps.
pack	string	A pack id from a result ("kn:mini-skate"): only assets from that kit, to keep a game in one style.
sort	string
type	string
limit	integer
style	string
cursor	string	next_cursor from the previous page.

upload_file

The server cannot read the user's disk. This returns an upload id and the exact curl command that sends a local file (a mesh or picture) to it; run that command, then pass the id as the image or mesh of another tool. Uploads last 24 hours.

Argument	Type	Description
bytes*	integer	The file's size in bytes (ls -l or stat).
filename*	string	The file's name with its extension, e.g. "chest.glb".
content_type	string
