Stamp. Verify. Done.

One SDK to create cryptographic proofs of AI content origin and verify them anywhere.

What the SDK Does

Creates a cryptographic proof of origin for any AI-generated content
Computes a perceptual fingerprint that survives re-encoding and screenshots
Stores the proof in the 0byte registry for public verification
Verifies any content against the registry in a single call

Install

pip install 0byte

Stamp Content

Generate your AI content with any provider. Then call stamp() to create a verifiable proof.

from zerobyte import Client

client = Client(api_key="0b_key_...")

# Generate your content however you want, then stamp it
proof = client.stamp(
    content=image_bytes,
    content_type="image/png",
    provider="stability",
    model="sdxl-turbo",
)

print(proof.id)          # "0b_proof_abc123"
print(proof.fingerprint) # perceptual content hash
print(proof.verify_url)  # "https://0byte.tech/proof/0b_proof_abc123"

Verify Content

Upload any content to check if it exists in the registry — even after re-encoding or screenshotting.

# Verify any content against the registry
result = client.verify(content=some_image_bytes)

print(result.matched)     # True / False
print(result.confidence)  # fingerprint similarity score
print(result.proof)       # original proof if matched
