• Free Forever = No cost, no limits
• Your Vercel Site → API call to HF Space
• Result = Works everywhere! ✅

🐛 Troubleshooting

Build Failed?

• Make sure you selected Docker as SDK (not Gradio or Streamlit)
• Check all 3 required files are uploaded
• Wait 5-10 minutes for first build

503 Service Unavailable?

• Space is still building - check Logs tab
• Space went to sleep - first request wakes it up (30 sec delay)
• Make a test request to wake it up

Conversion Failed?

• Check file format is .docx, .doc, .odt, .rtf, or .txt
• File size should be < 50MB
• Test locally first with curl

API URL Not Working?

• Copy exact URL from your Space (should end with .hf.space)
• Don't add /convert to env variable - just base URL
• Check it's accessible in browser
