tauth-sdk

Python SDK for Tauth — sign media files with C2PA content credentials and register provenance on Ethereum.

Installation

pip install tauth-sdk

Quick start

from tauth import TauthClient

client = TauthClient(api_key="tk_...")

# Sign a file
result = client.sign("photo.jpg", creator="Alice Smith", description="Product launch")
print(result["tx_hash"])      # Ethereum transaction hash
print(result["download_url"]) # Signed file URL

# Verify a file
info = client.verify_file("signed_photo.jpg")
print(info["valid"])    # True
print(info["manifest"]) # C2PA manifest contents

# List all signed assets
assets = client.list_assets()

API key

Generate an API key from your Tauth dashboard or via the API:

curl -X POST https://api.tauth.io/org/api-keys \
  -H "Authorization: Bearer <jwt>" \
  -H "Content-Type: application/json" \
  -d '{"name": "production", "scopes": ["sign", "verify"]}'

You can also set TAUTH_API_KEY in your environment instead of passing api_key directly.

Supported file types

JPEG, PNG, WebP, MP4, PDF
