TryMe Backend — Node/Express API

---

Overview

This backend provides:

• /tryon endpoint (garment + selfie → IDM-VTON try-on generation)
• /reverse-search endpoint (temporary garment hosting → Google Lens search)
• Serves static files under /public/reverse/
• Falls back to a mock result when HF quota is exhausted

Built for the TryMe Chrome Extension.

Hugging Face Token & ZeroGPU Limitations

IDM-VTON runs on Hugging Face ZeroGPU free tier.
Key caveats:

• Daily GPU minutes are limited
• API calls may still behave as anonymous
• When quota is exceeded:
  • Hugging Face returns 500 errors
  • Backend automatically returns a mock preview
• Daily quota resets every 24 hours
• Recommended to fork IDM-VTON for your own quota pool

Google Lens Reverse Image Search

The /reverse-search endpoint:

1. Accepts garmentDataUrl
2. Converts it to a JPEG file
3. Stores it in public/reverse/
4. Returns a Google Lens upload-by-URL search link

Caveat:

• Lens URLs are undocumented
• Implementation works as of version 1.0 (2025-11)
• May break if Google changes Lens behavior
