auctra (Python SDK)

Stage 0/1 Python client — same Authority Protocol as @auctra/sdk.

Requires Python 3.9+.

pip install auctra==0.2.6
# local dev: pip install -e packages/python-sdk

Quick start (with intent anchor)

High-risk actions require create_intent first, then pass the returned intent (id + anchor_token) on execute:

from auctra import Auctra

client = Auctra(api_key="auctra_...", base_url="https://app.auctra.tech")

agent_id = "your-agent-uuid"
expires_at = "2027-01-01T00:00:00Z"

client.authority.issue(
    subject=agent_id,
    capabilities=["send_payment"],
    expires_at=expires_at,
    max_amount=500,
    currency="USD",
)

created = client.create_intent(
    title="Pay matched vendor invoices",
    intent_type="payment",
    risk_level="high",
    max_risk_level="critical",
    allowed_action_types=["send_payment"],
    expires_at=expires_at,
)
intent = created["intent"]

preview = client.action.evaluate(
    agent_id=agent_id,
    action_type="send_payment",
    payload={"amount": 50, "currency": "USD"},
    intent=intent,
)

decision = client.action.execute(
    agent_id=agent_id,
    action_type="send_payment",
    payload={"amount": 50, "currency": "USD", "target": "vendor:acme"},
    intent=intent,
    action={
        "target": "vendor:acme",
        "description": "Net-30 invoice payment",
        "risk_level": "medium",
    },
)

print(decision["decision"])
client.evidence.verify(payload=decision["evidence_payload"], evidence=decision["evidence"])

New-client gotcha

Sending only claimed_intent_id (without intent_anchor_token or the intent object) returns require_approval with a reason about the missing anchor. Pass intent= from create_intent, or set both claimed_intent_id and intent_anchor_token explicitly.

See docs/integrations/intent-anchors.md.
