artemis-provenance-sdk

Thin Python client for the Artemis Provenance data plane — mark and verify AI-generated media (image · video · audio) for EU AI Act Article 50(2) compliance. The SDK contains no marking logic; it serializes calls to the data-plane container the customer runs in their own network, so content never leaves the VPC.

pip install artemis-provenance-sdk

Usage

from artemis_provenance_sdk import Client, MarkingUnavailableError

pv = Client(endpoint="http://provenance-dp.internal:8080", api_key="...")

# Mark an asset at the end of your generation pipeline.
try:
    marked = pv.mark_image(image_bytes, app_id="avatar-studio",
                           context={"title": "Generated avatar"})
    # marked.bytes  -> the marked output to ship
    # marked.event_id, marked.payload_id, marked.sha256, marked.marks
except MarkingUnavailableError:
    # Decide fail-open (ship unmarked — a compliance gap) vs fail-closed.
    ...

# Verify locally — content never leaves your network; only the id is resolved.
result = pv.verify(image_bytes, content_type="image")
# result["result"] == "matched" | "no-match", result["event"], result["checks"], result["local"]

There is also a file convenience wrapper:

marked = pv.mark_image_file("out/hero.png", app_id="avatar-studio")

Fail modes

MarkingUnavailableError is catchable so your pipeline chooses fail-open vs fail-closed consciously — document the compliance implications of each.

Typing

The package ships a py.typed marker; Client, MarkedAsset and VerifyResult are fully typed for editor/mypy support.
