curl -H "Authorization: ApiKey $VERGING_API_KEY" \
https://verging.ai/api/v1/auth/me
Response: {"email":"...","name":"...","credits":100}
2. Get Upload URL (Form Data - NOT JSON)
# ⚠️ MUST use -F (multipart form-data), NOT -d (JSON)
curl -X POST https://verging.ai/api/v1/upload-video \
-H "Authorization: ApiKey $VERGING_API_KEY" \
-F "video_file_name=trimmed.mp4" \
-F "job_type=face-swap"

}
}
3. Upload Video to R2 (PUT with binary body)
curl -X PUT -T /tmp/verging-faceswap/trimmed.mp4 \
-H "Content-Type: video/mp4" \
"<presigned_url_from_step_2>"
4. Create Face Swap Job (Multipart — face image uploaded here directly)
# ⚠️ swap_image is a FILE upload (@path) — the server uploads it to R2 internally
# ⚠️ You do NOT need to separately upload the face image via /upload-video
curl -X POST https://verging.ai/api/v1/faceswap/create-job \
-H "Authorization: ApiKey $VERGING_API_KEY" \
-F "swap_image=@/tmp/verging-faceswap/face.jpg" \
-F "file_name=video.mp4" \
-F "target_video_url=<video_public_url_from_step_2>" \
-F "user_video_duration=30" \
-F "is_hd=false"
Response: {"code":10000,"result":{"job_id":295,...}}
5. Poll Job Status
curl -H "Authorization: ApiKey $VERGING_API_KEY" \

Response: [{"id":295,"status":"COMPLETED","progress":100,"result_url":"https://..."}]
Execution Flow (Follow Exactly)
- Parse args → extract video path/URL, face path/URL, options
- Download remote resources (if URLs provided):
- Video URL →
yt-dlp "URL" -o /tmp/verging-faceswap/input.mp4 - Image URL →
curl -L -o /tmp/verging-faceswap/face.jpg "URL"
- Video URL →
- Get video duration →
ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 video.mp4 - Trim if needed (--start/--end or duration > 30s):
ffmpeg -i input.mp4 -ss <start> -to <end> -c:v libx264 -c:a aac /tmp/verging-faceswap/trimmed.mp4 - Check credits → GET /api/v1/auth/me (need duration × 1 or ×3 for HD)
- Upload video only → POST /upload-video (Form Data) → PUT to presigned URL
- Create job → POST /faceswap/create-job (face image goes as multipart file directly via
swap_image=@path, no separate upload needed) - Poll status → GET /faceswap/jobs?job_ids=X every 5 seconds until COMPLETED
- Return/download result → show result_url, optionally curl download
Critical Notes
- Use
Authorization: ApiKey <key>(recommended) —Bearer <key>also works - Only the VIDEO needs separate upload via /upload-video + PUT to presigned URL
- Face image is uploaded directly in create-job as multipart
swap_image=@path— no separate upload step /upload-videouses Form Data (-F) — NOT JSON (-d)- Max video duration: 30 seconds — trim longer videos first
- Temp directory:
/tmp/verging-faceswap/— create withmkdir -p - If yt-dlp is unavailable, ask user to download video manually
Credit Consumption
