Human Presence Verification for Python
Presence SDK — verify human presence before consequential actions execute.
Applications send intent and context. Presence verifies the person. Decionis decides whether execution proceeds.
Install
python -m pip install decionis-presence
export PRESENCE_API_KEY='presence_sk_…'
Thirty seconds to a verdict
import os
import uuid
from presence_sdk import Client
presence = Client(os.environ["PRESENCE_API_KEY"])
result = presence.run_sandbox_scenario("allow", f"quickstart-{uuid.uuid4().hex}")
print(result["policy_verdict"])
The fixture is signed with evidence_class: sandbox_fixture and always runs in Shadow
Mode. Tenant credentials belong on trusted servers only.
