description	Animate old photos into AI-generated videos using the Animate Old Photos API. Upload a photo, generate a 5-second animation video, and download the result. Use when the user wants to animate a photo, bring an old photo to life, turn old photos into videos, create a video from a still image, or convert a photo to video. Requires a paid API key from https://animateoldphotos.org

Animate Old Photos

Animate old photos into AI-generated videos via the Animate Old Photos API. The agent uploads a photo, submits an animation task, polls for completion, and downloads the resulting MP4 video.

Prerequisites

This is a paid service. You need an API key and credits.

• Official Website: Animate Old Photos
• Get your API key: Profile > API Key
• Purchase credits: Buy Credits

Each animation costs 3 credits. View pricing plans

System requirements: curl and jq must be available in the shell.

Workflow

Before starting

1. Ask the user for their API key if environment variable AOP_API_KEY is not set.
2. Ask for the image path. Verify the file exists, is JPEG or PNG, and is under 10 MB.
3. Ask for an optional prompt describing desired motion (e.g. "grandmother smiling and waving"). If omitted the AI auto-generates motion.
4. Confirm with the user: "This will cost 3 credits. Proceed?"

Step 1 — Authenticate

Exchange the API key for a short-lived access token and check the credit balance.

API_KEY="${AOP_API_KEY}"
AUTH=$(curl -s -X POST https://animateoldphotos.org/api/extension/auth \
  -H "Content-Type: application/json" \
  -d "{\"licenseKey\":\"${API_KEY}\"}")
TOKEN=$(echo "$AUTH" | jq -r '.accessToken')
CREDITS=$(echo "$AUTH" | jq -r '.creditBalance')
echo "Authenticated. Credits available: $CREDITS"

If accessToken is missing or error_code is 4010/4011, tell the user their API key is invalid and link to https://animateoldphotos.org/profile/interface-key.

If credits < 3, tell the user to purchase more at https://animateoldphotos.org/pricing and stop.

Step 2 — Upload image

Get a presigned upload URL, then PUT the image binary to cloud storage.

IMAGE_PATH="photo.jpg"
FILE_SIZE=$(stat -f%z "$IMAGE_PATH" 2>/dev/null || stat -c%s "$IMAGE_PATH" 2>/dev/null)
CONTENT_TYPE="image/jpeg"  # use image/png for .png files

UPLOAD=$(curl -s -X POST https://animateoldphotos.org/api/extension/upload-token \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d "{\"fileName\":\"$(basename "$IMAGE_PATH")\",\"contentType\":\"${CONTENT_TYPE}\",\"fileSize\":${FILE_SIZE}}")
UPLOAD_URL=$(echo "$UPLOAD" | jq -r '.uploadUrl')
KEY=$(echo "$UPLOAD" | jq -r '.key')
PUBLIC_URL=$(echo "$UPLOAD" | jq -r '.publicUrl')

curl -s -X PUT "$UPLOAD_URL" \
  -H "Content-Type: ${CONTENT_TYPE}" \
  --data-binary "@${IMAGE_PATH}"
echo "Image uploaded."

Step 3 — Finalize upload

Confirm the upload and receive the encrypted payload needed for task submission.

FINALIZE=$(curl -s -X POST https://animateoldphotos.org/api/extension/upload-finalize \
  -H "Authorization: Bearer $TOKEN" \
  -F "key=${KEY}" \
  -F "publicUrl=${PUBLIC_URL}")
IMAGE_URL=$(echo "$FINALIZE" | jq -r '.url')
SS_MESSAGE=$(echo "$FINALIZE" | jq -r '.message')
DNT=$(echo "$FINALIZE" | jq -r '.dnt')
echo "Upload finalized."

Step 4 — Submit animation task

Submit the animation job. The Ss header must contain the message value from Step 3.

PROMPT=""  # optional user prompt
TASK=$(curl -s -X POST https://animateoldphotos.org/api/extension/animate \
  -H "Authorization: Bearer $TOKEN" \
  -H "Ss: ${SS_MESSAGE}" \
  -F "prompt=${PROMPT}" \
  -F "input_image_url=${IMAGE_URL}" \
  -F "dnt=${DNT}" \
  -F "type=m2v_img2video" \
  -F "duration=5" \
  -F "public=false")
TASK_ID=$(echo "$TASK" | jq -r '.taskId')
TASK_DNT=$(echo "$TASK" | jq -r '.dnt')
TASK_DID=$(echo "$TASK" | jq -r '.did')
echo "Task submitted (ID: $TASK_ID). Polling for result..."

If the response contains error_code 999990 or 10009, the user has insufficient credits — link to https://animateoldphotos.org/pricing.

Step 5 — Poll until done

Poll every 30 seconds. Typical completion time is 2–5 minutes.

OUTPUT="output.mp4"
while true; do
  sleep 30
  STATUS=$(curl -s -G "https://animateoldphotos.org/api/extension/animate" \
    --data-urlencode "taskId=${TASK_ID}" \
    --data-urlencode "dnt=${TASK_DNT}" \
    --data-urlencode "did=${TASK_DID}" \
    --data-urlencode "type=m2v_img2video" \
    -H "Authorization: Bearer $TOKEN")

  ERR_MSG=$(echo "$STATUS" | jq -r '.message // empty')
  if [ -n "$ERR_MSG" ]; then
    echo "Task failed: $ERR_MSG"
    break
  fi

  S=$(echo "$STATUS" | jq -r '.status')
  RESOURCE=$(echo "$STATUS" | jq -r '.resource // empty')
  if [ "$S" -ge 99 ] 2>/dev/null && [ -n "$RESOURCE" ]; then
    curl -s -o "$OUTPUT" "$RESOURCE"
    echo "Video saved to $OUTPUT"
    break
  fi
   

Report the saved video path to the user when done.

One-liner alternative

You can run the full pipeline with the bundled script:

bash scripts/animate.sh <API_KEY> <IMAGE_PATH> [PROMPT] [OUTPUT_PATH]

See scripts/animate.sh for details.

Error Handling

error_code	Meaning	Action
4010	Invalid API key	Direct user to get a key
4011	API key expired	Direct user to renew key
999998	Access token invalid	Re-run Step 1 to get a new token
999990	Insufficient credits	Direct user to buy credits
10009	Insufficient credits	Direct user to buy credits

For network errors, retry up to 3 times with exponential backoff (2s, 4s, 8s).

Interaction Flow

1. Trigger: User says "animate this photo", "turn old photos into videos", "bring this photo to life", or similar.
2. Gather inputs: Ask for API key (if AOP_API_KEY not set), image path, and optional prompt.
3. Confirm: "This will cost 3 credits. You currently have {N} credits. Proceed?"
4. Execute: Run Steps 1–5, reporting progress at each stage.
5. Complete: "Your animated video has been saved to {output_path}."
6. On error:
   • Insufficient credits → "You need more credits. Purchase at: https://animateoldphotos.org/stripe"
   • Invalid API key → "Your API key is invalid or expired. Get one at: https://animateoldphotos.org/profile/interface-key"
   • Task failure → Show the error message and suggest the user retry or adjust the prompt.

Constraints

• Supported formats: JPEG, PNG only
• Max file size: 10 MB
• Min image dimension: 300 × 300 px
• Cost per animation: 3 credits
• Video duration: 5 seconds
• Typical processing time: 2–5 minutes
