vorim

Official Python SDK for Vorim AI — the identity, permissions, and audit layer for AI agents.

Vorim AI provides cryptographic agent identities (Ed25519), fine-grained permissions (7 scopes), immutable audit trails, and trust scoring (0-100) for production AI agent deployments. Built for the traceability and audit-trail obligations of frameworks like the EU AI Act.

Quick Start

from vorim import Vorim

vorim = Vorim(api_key="agid_sk_live_...")

# Register an agent (returns Ed25519 keypair, private key shown once)
result = vorim.register(
    name="invoice-processor",
    capabilities=["read_documents", "extract_data"],
    scopes=["agent:read", "agent:execute"],
)
print(result.agent.agent_id)    # agid_acme_a1b2c3d4
print(result.agent.trust_score) # 50

# Check permissions (<5ms via Redis)
check = vorim.check(result.agent.agent_id, "agent:execute")

if check.allowed:
    # Emit audit event
    vorim.emit(
        agent_id=result.agent.agent_id,
        event_type="tool_call",
        action="process_invoice",
        resource="INV-2026-0042",
        result="success",
        latency_ms=142,
    )

# Verify any agent's trust (public, no auth required)
trust = vorim.verify(result.agent.agent_id)
print(f"Trust score: {trust.trust_score}/100")

Async Client

from vorim import AsyncVorim

async with AsyncVorim(api_key="agid_sk_live_...") as vorim:
    result = await vorim.register(
        name="my-agent",
        capabilities=["search"],
        scopes=["agent:read"],
    )

    trust = await vorim.verify(result.agent.agent_id)
    print(f"Trust score: {trust.trust_score}/100")

API Reference

Vorim(api_key, base_url?, timeout?, auto_sign=True)

Module-level helpers: canonical_payload_v1(event) and canonical_payload_v0(event) (return the bytes that get signed) and sign_payload(payload, private_key_pem) (returns ed25519:<base64>).

AsyncVorim has the same interface with await on all methods.

Per-event signing (auto-signing)

From v3.7.0, every audit event is signed at source with the agent's Ed25519 private key — no code change required. register() caches the returned key in memory and emit() attaches the signature transparently.

Canonical form. Since 3.7.0 the SDK defaults to v1 canonical form: RFC 8785 JSON Canonicalization Scheme (JCS) over the whole event minus signature and canonical_form. v1 brings metadata, replayable-evidence fields (model_version, tool_catalogue_hash, system_prompt_hash, prev_event_hash), and delegation context (on_behalf_of, delegator_agent_id, delegation_chain_id, delegation_depth) under the signature. The previous v0 form was a pipe-joined six-field string event_type|action|resource|input_hash|output_hash|result and is now deprecated — passing canonical_form="v0" explicitly still works for verifier-compat scenarios but logs a deprecation warning. Use @vorim/verify@0.2.0+ (or the v1 helpers in this package) to verify v1 events offline.

result = vorim.register(name="agent", capabilities=[], scopes=[])

# Auto-signed. The signature is attached before the request leaves the process.
vorim.emit(
    agent_id=result.agent.agent_id,
    event_type="tool_call",
    action="transfer_funds",
    result="success",
)

To verify signatures server-side, the API operator sets VORIM_VERIFY_AUDIT_SIGNATURES=true.

Restoring keys across process restarts. The in-memory keyring is lost on restart. Load the private key from your secret store:

vorim.use_agent_key(agent_id, private_key_pem)
vorim.forget_agent_key(agent_id)  # revoke from memory

Opting out. Per event with sign=False, or globally with auto_sign=False:

vorim.emit(agent_id=..., event_type=..., action=..., result=..., sign=False)
vorim = Vorim(api_key=..., auto_sign=False)

Runtime Control (gate actions before they happen)

Ask Vorim whether an action should proceed before your agent performs it. before_action() returns a typed decision and, by default, raises on deny (a denial is in the response body, not the HTTP status).

from vorim import Vorim, VorimDeniedError

vorim = Vorim(api_key="agid_sk_live_...")

try:
    decision = vorim.before_action(
        agent_id="agid_acme_a1b2c3d4",      # always the public agid_* id
        action_type="tool_call",
        action_target="sendEmail",
        required_scope="agent:communicate",
        payload={"to": "customer@example.com", "body": "..."},
    )

    payload = decision.modified_payload or {"to": "customer@example.com"}

    if decision.decision in ("allow", "modify"):
        send_email(payload)
    elif decision.decision == "escalate":
        resolved = vorim.wait_for_decision_resolution(decision.decision_id)
        if resolved.decision == "allow":
            send_email(payload)

    # Link the post-action audit event back to the decision.
    vorim.emit(
        agent_id="agid_acme_a1b2c3d4",
        event_type="tool_call",
        action="sendEmail",
        result="success",
        decision_id=decision.decision_id,   # correlates audit ↔ decision
    )
except VorimDeniedError as err:
    print("Action denied:", err.decision.reason)

Verdicts: allow · deny (raises VorimDeniedError by default) · modify (use decision.modified_payload) · escalate (poll wait_for_decision_resolution) · fallback.

modify is client-cooperative. Vorim returns the sanitised modified_payload; your agent must send it in place of the original. The platform does not sit inline and does not currently enforce that you do — carry decision_id into the matching emit() so the action stays auditable.

Fail-open: if the decision API is unreachable, before_action() returns a synthetic fallback decision. Pass runtime_fail_open=False to the constructor to fail closed. A reachable server returning deny always denies. AsyncVorim exposes the same async methods.

Requires an API key with the runtime:decide scope and a Growth+ plan. modify verdicts come from policy rules provisioned by Vorim (rule-authoring API ships in a later release).

Permission Scopes

Payload Privacy

Your prompts and model outputs never have to reach Vorim. The audit event carries a digest of them, computed in your process.

A bare SHA-256 of a prompt is not a commitment, it is a lookup key: prompts are low-entropy and usually templated, so anyone holding the digest and the template recovers the content by trying candidates. Use a keyed commitment for anything a human or a model wrote.

from vorim import Vorim, commit_payload

key = os.environ["VORIM_COMMITMENT_KEY"]   # never sent to Vorim

v.emit(
    agent_id=agent.agent_id,
    event_type="tool_call",
    action="invoice.refund",
    result="success",
    input_hash=commit_payload(prompt, key),        # hmac-sha256:...
    output_hash=commit_payload(completion, key),
)

Keep hash_payload for content that is already high-entropy. To disclose later, hand the verifier the content and the key; they recompute and compare.

Refuse to send content at all:

v = Vorim(api_key=..., no_payload=True)          # no_payload_max_metadata_chars=256
v.emit(..., metadata={"prompt": full_prompt})    # raises VorimError PAYLOAD_BLOCKED

Not the same as the server-side Zero Data Retention setting, which drops metadata when we persist it, after the content has crossed the network. This means it never left your process.

Every emit returns a stable content digest beside the event id, and event_digest(event) recomputes it locally. Byte-identical to @vorim/sdk and @vorim/verify.

Framework Integrations

LangChain / LangGraph

from vorim import Vorim
from vorim.integrations.langchain import vorim_tool, VorimCallbackHandler

vorim = Vorim(api_key="agid_sk_live_...")

@vorim_tool(vorim, agent_id="agid_acme_...", permission="agent:execute")
def search(query: str) -> str:
    """Search documents."""
    return f"Results for {query}"

# search() is now a standard LangChain tool with built-in permission checks + audit

CrewAI

from vorim import Vorim
from vorim.integrations.crewai import register_crew

vorim = Vorim(api_key="agid_sk_live_...")

crew = register_crew(vorim, {
    "crew_name": "content-pipeline",
    "members": [
        {
            "role": "researcher",
            "name": "crew-researcher",
            "capabilities": ["web_search"],
