​
Deepfake Detection API

The Deepfake Detection API allows you to detect audio and video deepfakes and verify voice identity.

​
Audio Deepfake Detection

​
/detection/audio
Detect if an audio file is a deepfake

​
Request Parameters

​
audio_file
file
required
The audio file to analyze
​
sensitivity
float
Optional. Detection sensitivity (0.0-1.0). Higher values increase detection sensitivity but may lead to more false positives. Default: 0.5

​
Example Request

curl -X POST "https://api.truly.ws/detection/audio" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "audio_file=@sample.wav" \
  -F "sensitivity=0.7"

​
Example Response

{
  "is_deepfake": true,
  "confidence": 0.92,
  "analysis": {
    "artifacts_detected": true,
    "voice_inconsistencies": true,
    "synthetic_patterns": true
  },
  "processing_time": 1.2
}

​
Video Deepfake Detection

​
/detection/video
Detect if a video contains deepfaked content

​
Request Parameters

​
video_file
file
required
The video file to analyze
​
analyze_audio
boolean
Optional. Whether to analyze the audio track as well. Default: true
​
sensitivity
float
Optional. Detection sensitivity (0.0-1.0). Default: 0.5

​
Example Request

curl -X POST "https://api.truly.ws/detection/video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "video_file=@sample.mp4" \
  -F "analyze_audio=true" \
  -F "sensitivity=0.6"

​
Example Response

{
  "is_deepfake": true,
  "confidence": 0.89,
  "analysis": {
    "face_manipulation_detected": true,
    "audio_manipulation_detected": false,
    "inconsistent_blinking": true,
    "unnatural_facial_movements": true
  },
  "processing_time": 3.5
}

​
Voice Verification

​
/verification/voice
Verify if two voice samples are from the same person

​
Request Parameters

​
audio_file1
file
required
The first audio file
​
audio_file2
file
required
The second audio file to compare with
​
threshold
float
Optional. Similarity threshold (0.0-1.0). Higher values require stronger similarity to consider a match. Default: 0.7

​
Example Request

curl -X POST "https://api.truly.ws/verification/voice" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "audio_file1=@sample1.wav" \
  -F "audio_file2=@sample2.wav" \
  -F "threshold=0.75"

​
Example Response

{
  "same_person": true,
  "similarity_score": 0.86,
  "confidence": 0.92,
  "processing_time": 1.8
}
