Subject: Hunyuan 3D API Access

Hello,

I'm trying to use the Hunyuan 3D API (V20250513) but receiving error
"接口不存在" despite the API version date being May 2025.

Setup:

• SDK: TencentCloudSDK.Ai3d v3.0.1347
• Region: ap-singapore (only supported region per docs)
• Account: Trial (200 credits)
• Current Date: December 2025
• API Version Date: May 2025

The API version suggests May 2025 release, but it's now December.
Does my account need activation for this service?

Error: 接口不存在

Please advise.

Thank you!
