authenta 0.1.1

Python SDK for the Authenta API to detect deepfakes and manipulated media

Authenta SDK Documentation

Welcome to the official documentation for the Authenta Python SDK. This library allows you to integrate state-of-the-art deepfake and manipulated media detection into your Python applications.

---

1. Getting Started

Installation

You can install the SDK via pip for production use or install from source for local development.

Option A: Install from PyPI (Recommended)

pip install authenta

Option B: Local Development If you want to modify the SDK source code:

git clone https://github.com/phospheneai/authenta-python-sdk.git
cd authenta-python-sdk
pip install -e .

Authentication & Initialization

To use the SDK, you must initialize the AuthentaClient with your API credentials.

from authenta import AuthentaClient

client = AuthentaClient(
    base_url="https://platform.authenta.ai",
    client_id="YOUR_CLIENT_ID",
    client_secret="YOUR_CLIENT_SECRET",
)

2. Models & Capabilities

Authenta provides specialized models for different media types. You select the model using the model_type parameter in SDK methods.

Model Type	Modality	Capability
AC-1	Image	AI-Generated Image Detection: Identifies images created by Generative AI (e.g., Midjourney, Stable Diffusion) or manipulated via editing tools.
DF-1	Video	Deepfake Video Detection: Detects face swaps, reenactments, and other facial manipulations in video content.

3. Workflows

Quick Detection (Synchronous)

Use the .process() method to handle uploading and waiting for results in a single blocking call. This is ideal for scripts or simple integrations.

# Example: Detect AI-generated image
media = client.process("samples/nano_img.png", model_type="AC-1")

print(f"Media ID: {media['mid']}")
print(f"Status: {media['status']}")
print(f"Is Fake?: {media.get('fake')}")

Async Upload & Polling

For non-blocking workflows (e.g., web servers), use a two-step process: upload first, then poll for status using the Media ID (mid).

# 1. Initiate Upload
upload_meta = client.upload_file("samples/video.mp4", model_type="DF-1")
mid = upload_meta["mid"]
print(f"Upload started. Media ID: {mid}")

# ... perform other tasks ...

# 2. Check Status Later
final_media = client.wait_for_media(mid)
if final_media["status"] == "PROCESSED":
    print(f"Result: {final_media.get('fake')}")

Visualizing Results

The SDK includes a visualization module to generate visual overlays (heatmaps and bounding boxes) to help you interpret detection results.

1. Heatmaps (Images & Video) Generate a visual heatmap indicating manipulated regions.

from authenta.visualization import save_heatmap
media = client.process("data_samples/nano_img2.png", model_type="AC-1")
# simply pass the media and output dir 
save_heatmap(
    media=media,
    out_path="results/image_heatmap.jpg",
    model_type="AC-1",
)

Generate an activation heatmap indicating manipulated regions for faceswap detection .

from authenta.visualization import *
media = client.process("data_samples/test_00000121.mp4", model_type="DF-1")
save_heatmap(
    media,
    out_path="results/deepfake_heatmap.mp4",
    model_type="DF-1",
)

2. Bounding Box Video (DF-1 Only) Draw detection boxes around faces in a deepfake video.

from authenta.visualization import *

media = client.process("data_samples/test_00000121.mp4", model_type="DF-1")

save_bounding_box_video(
    media,
    src_video_path="data_samples/test_00000121.mp4",
    out_video_path="results/analyzed_video.mp4",
)

4. API Reference

Class: AuthentaClient

__init__(base_url, client_id, client_secret)

Initializes the client session.

process(path: str, model_type: str, interval: float = 5.0, timeout: float = 600.0) -> Dict

A high-level wrapper that combines upload and polling.

• Returns: A dictionary containing the final processed media state.
• Raises: TimeoutError if processing exceeds timeout.

upload_file(path: str, model_type: str) -> Dict

Uploads a file to the Authenta platform.

• path: Local path to the image or video file.
• model_type: AC-1 (Image) or DF-1 (Video).
• Returns: Dictionary with initial metadata (including mid).

wait_for_media(mid: str, interval: float = 5.0, timeout: float = 600.0) -> Dict

Blocks execution until the media status becomes PROCESSED or FAILED.

• mid: The Media ID returned from upload_file.

get_media(mid: str) -> Dict

Retrieves the current status and details of a specific media record.

list_media(**params) -> Dict

Lists historical media records.

• params: Query parameters like page, pageSize.

delete_media(mid: str) -> None

Permanently removes a media record and its associated data from the platform.
