Use Remesh with Comfy Router

API Reference for meshy/remesh, served by Comfy Router from Meshy.

Quick start

Create a key in your Comfy workspace and export it as COMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP. Model ID: meshy/remesh Endpoint: POST https://api.comfy.org/v2/models/meshy/remesh

from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment.
# The SDK automatically creates an idempotency key and reuses it for automatic retries.
with Comfy() as client:
    result = client.models.run(
        "meshy/remesh",
        {
            "input_task_id": "0193abcd-0000-0000-0000-000000000000",
            "origin_at": "bottom",
            "resize_height": 1,
            "target_formats": ["glb", "fbx"],
            "target_polycount": 50000,
            "topology": "quad",
        },
    )

print(result)

import { comfy } from "@comfyorg/sdk";

// Reads COMFY_API_KEY from the environment.
// The SDK automatically creates an idempotency key and reuses it for automatic retries.
const { data } = await comfy.models.run("meshy/remesh", {
  input_task_id: "0193abcd-0000-0000-0000-000000000000",
  origin_at: "bottom",
  resize_height: 1,
  target_formats: ["glb", "fbx"],
  target_polycount: 50000,
  topology: "quad",
});

console.log(data);

Schema

Input

boolean

default:"false"

If true, only changes the format of the input model file, ignoring other inputs like topology, resize_height, and target_polycount.

string

The ID of the completed Image to 3D or Text to 3D task you wish to remesh. Required if model_url is not provided.

string

A publicly accessible URL or data URI to a 3D model. Supported formats glb, gltf, obj, fbx, stl. Required if input_task_id is not provided.

string

Position of the origin.Possible values: bottom, center, “

number

default:"0"

Resize the model to a certain height measured in meters. 0 means no resizing.

`glb`, `fbx`, `obj`, `usdz`, `blend`, `stl`[]

default:"[\"glb\"]"

A list of target formats for the remeshed model.

integer

default:"30000"

Specify the target number of polygons in the generated model. Valid range is 100 to 300,000.Range: 100 to 300000

string

default:"\"triangle\""

Specify the topology of the generated model.Possible values: quad, triangle

Generated from the schema Router serves at GET /v2/models/meshy/remesh/openapi.json, the same document it validates a call against before the request reaches the provider.

string

Downloadable URL to the USDZ file.

integer

The count of preceding tasks. Only meaningful when status is PENDING.

integer

Progress of the task. 0 if not started, 100 when succeeded.Range: 0 to 100

integer

Timestamp of when the task was started, in milliseconds. 0 if not started.Format: int64

string

required

Possible values: SUCCEEDED

object

Error object that contains the error message if the task failed.

string

Detailed error message.

string

Type of the Remesh task.Possible values: remesh

Before you ship

The SDKs create an Idempotency-Key and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes. When a request fails, Router sends an X-Comfy-Error-Type response header explaining why. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Using the Router API

Model discovery, validation errors, retries, and billing.

Limitations

What Router does not do today, and what to use instead.
