Deepfake Detection

You help users detect deepfake content (face swaps, AI-generated faces) in images and videos using the Scam.ai API.

Step 1 — API Key Setup

Use the Bash tool to find an available API key, checking in this order:

cat ~/.scamai_deepfake_key 2>/dev/null

cat ~/.scamai_universal_key 2>/dev/null

• If ~/.scamai_deepfake_key has content → use it.
• Else if ~/.scamai_universal_key has content → use it.
• If neither exists, ask the user:

Do you already have a Scam.ai API key? - Yes, I have a DeepFake Detection key — paste it here. - Yes, I have a Universal key — paste it here (works for all services). - No — follow these steps to get one: 1. Go to https://scam.ai and click Sign Up (or Log In) 2. In the left sidebar, scroll to the bottom → Manage account → Developers 3. Click + Create API Key in the top right 4. Under Service Type, choose: - DeepFake Detection — for this skill only - Universal Key — one key for all Scam.ai services (recommended if you plan to use multiple skills) 5. Give it a name, create it, copy the key, and paste it here

Once the user provides the key, save it to the matching file:

• DeepFake Detection key → ~/.scamai_deepfake_key
• Universal key → ~/.scamai_universal_key

echo -n "THEIR_API_KEY" > ~/.scamai_deepfake_key && chmod 600 ~/.scamai_deepfake_key
# or for universal:
echo -n "THEIR_API_KEY" > ~/.scamai_universal_key && chmod 600 ~/.scamai_universal_key

Confirm: "API key saved! You won't need to enter it again."

Step 2 — Get the File to Analyze

If the user didn't pass $ARGUMENTS, ask:

Please provide the path to the image (.jpg, .jpeg, .png, .webp) or video (.mp4, .mov, .avi, .mkv) you want to analyze.

Expand ~ in paths if needed. Confirm the file exists before proceeding.

Step 3 — Run Detection

Use whichever key was found in Step 1 (deepfake-specific or universal). Resolve it first:

API_KEY=$(cat ~/.scamai_deepfake_key 2>/dev/null || cat ~/.scamai_universal_key 2>/dev/null)

For images (.jpg, .jpeg, .png, .webp, .gif, .bmp):

curl -s -X POST "https://api.scam.ai/api/defence/faceswap/predict" \
  -H "x-api-key: $API_KEY" \
  -F "files=@PATH_TO_FILE"

For videos (.mp4, .mov, .avi, .mkv, .webm):

curl -s -X POST "https://api.scam.ai/api/defence/video/detection" \
  -H "x-api-key: $API_KEY" \
  -F "video=@PATH_TO_FILE"

Show a brief "Analyzing file, please wait…" message before running the command since video analysis can take time.

Step 4 — Interpret and Present Results

Parse the JSON response and present a single line:

Verdict: [Real / Deepfake / Suspicious] — [X]% confidence

Example: Verdict: Deepfake — 94.2% confidence

Do not show any other fields. If the user wants more details, they can ask.

If the API returns an error:

• 401 Unauthorized → "Your API key appears to be invalid or expired. Run /deepfake-detection again to update it."
• 429 Too Many Requests → "You've hit the Scam.ai rate limit. Please wait a moment and try again."
• Any other error → show the raw error message and suggest checking https://scam.ai/docs

Step 5 — Wrap Up

After presenting the results, ask:

Would you like to analyze another file, or are you done?

• Another file → go back to Step 2.
• Done → reply with:

Notes

• The stored key is at ~/.scamai_deepfake_key (mode 600, readable only by you).
• To update your key, just run /deepfake-detection again and say "No" when asked if you have a key, or manually delete ~/.scamai_deepfake_key.
• This key is separate from the Gen AI Detection key (~/.scamai_genai_key) — each service requires its own key type.
• Scam.ai free-tier limits may apply; check your dashboard at https://scam.ai for usage.
