Use Hunyuan 3D Smart Topology with Comfy Router

Call tencent/hunyuan-3d-smart-topology through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for tencent/hunyuan-3d-smart-topology, served by Comfy Router from Tencent.

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: tencent/hunyuan-3d-smart-topology

Endpoint: POST https://api.comfy.org/v2/models/tencent/hunyuan-3d-smart-topology

Python

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(
        "tencent/hunyuan-3d-smart-topology",
        {
            "File3D": {
                "Type": "GLB",
                "Url": "https://vcg-test-1258344699.cos.ap-guangzhou.myqcloud.com/test/3d/test.glb",
            },
        },
    )

print(result)

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.
