Verdifax Python SDK
Cryptographic attestation for AI inference. Three lines: send a payload, get a signed manifest hash you can give to an auditor.
Install
pip install verdifax
Quickstart
import verdifax
receipt = verdifax.attest(
payload="hello verdifax",
program_id="a" * 64,
route_id="route-test",
registry_record_hash="b" * 64,
)
print(receipt.manifest_hash)
That's it. The receipt's manifest_hash is a 64-char SHA-256 that seals every input, every kernel execution ID, the hardware attestation, the ZK transcript, the formal verifier status, and the final VFA. Anyone with the same inputs can re-derive the same hash.
Configuration
By default the SDK talks to a Verdifax API at http://localhost:9090 (the orchestrator's REST server). Override with environment variables:
export VERDIFAX_API_URL=https://api.verdifax.example.com
export VERDIFAX_API_KEY=your-api-key
Or construct a client explicitly:
from verdifax import VerdifaxClient
client = VerdifaxClient(base_url="https://api.verdifax.example.com", api_key="...")
receipt = client.attest(payload="...", program_id="...", route_id="...", registry_record_hash="...")
Async
import asyncio
from verdifax import AsyncVerdifaxClient
async def main():
async with AsyncVerdifaxClient() as client:
receipt = await client.attest(
payload="hello verdifax",
program_id="a" * 64,
route_id="route-test",
registry_record_hash="b" * 64,
)
print(receipt.manifest_hash)
asyncio.run(main())
Verification
Re-derive the manifest hash from the same inputs and confirm it matches a previously issued receipt:
ok = client.verify(
manifest_hash=receipt.manifest_hash,
payload="hello verdifax",
program_id="a" * 64,
route_id="route-test",
registry_record_hash="b" * 64,
)
Helpers for popular providers
import verdifax
receipt = verdifax.attest_claude_response(
prompt="What is the boiling point of water?",
response="100 °C at sea level.",
program_id="a" * 64,
route_id="claude-route",
registry_record_hash="b" * 64,
)
There is also verdifax.attest_openai_response(...) with the same signature.
