Authentication Examples

# Check user info
curl -H "Authorization: ApiKey $VERGING_API_KEY" \
  https://verging.ai/api/v1/auth/me

# Step 1: Get presigned upload URL for image
curl -X POST -H "Authorization: ApiKey $VERGING_API_KEY" \
  -F "video_file_name=image.jpg" \
  -F "job_type=background-removal" \
  https://verging.ai/api/v1/upload-video

# The response contains:
# {
#   "result": {
#     "url": "https://...r2.cloudflarestorage.com/...jpg?X-Amz-...",
#     "public_url": "https://img.panpan8.com/background-removal/2026-03-11/xxx.jpg"
#   }
# }

# Step 2: Upload image to the presigned URL
curl -X PUT -T /path/to/image.jpg \
  "https://...presigned-url-from-step-1..."

# Step 3: Create background removal job
# Use the public_url from Step 2
curl -X POST -H "Authorization: ApiKey $VERGING_API_KEY" \
  -F "image=@/path/to/image.jpg" \
  -F "file_name=image.jpg" \
