Installation

pip install aira-sdk

Requires Python 3.9+.

Quick start

Three steps: authorize the action, execute it, notarize the outcome.

from aira import Aira

aira = Aira(api_key="aira_live_xxx")

# 1. Authorize — policies evaluate, denied actions raise AiraError
auth = aira.authorize(
    action_type="wire_transfer",
    details="Send EUR 75,000 to vendor-x",
    agent_id="payments-agent",
    model_id="claude-sonnet-4-6",
)

# 2. Execute
ref = send_wire(75000, to="vendor-x")

# 3. Notarize — mints an Ed25519 + RFC 3161 receipt
receipt = aira.notarize(
    action_id=auth.action_id,
    outcome="completed",
    outcome_details=f"Wire sent, ref={ref}",
)
print(receipt.signature)  # ed25519:base64url...

If the action requires human approval, auth.status returns "pending_approval" and you can enqueue it for review.

Universal receipts — Every action — authorized, denied, or failed — produces an Ed25519 receipt. The audit trail has zero gaps.

Core methods

Async support

AsyncAira mirrors every method on Aira. Use await and an async context manager.

from aira import AsyncAira

async with AsyncAira(api_key="aira_live_xxx") as aira:
    auth = await aira.authorize(
        action_type="contract_signed",
        details="Signed vendor agreement #1234",
        agent_id="procurement-agent",
    )
    if auth.status == "authorized":
        ref = await sign_contract(1234)
        await aira.notarize(
            action_id=auth.action_id,
            outcome="completed",
            outcome_details=f"signed, ref={ref}",
        )

Gateway

Route existing OpenAI or Anthropic calls through Aira. Every request is policy-checked and receipted with zero prompt changes.

from aira import gateway_openai_kwargs

client = openai.OpenAI(api_key="sk-...", **gateway_openai_kwargs(aira_api_key="aira_live_xxx"))

The Anthropic equivalent:

from aira import gateway_anthropic_kwargs

client = anthropic.Anthropic(**gateway_anthropic_kwargs(aira_api_key="aira_live_xxx"))

Both helpers return base_url and default_headers dicts. Self-hosted deployments can pass gateway_url to point at your own instance.

Framework integrations

gate intercepts before execution and can deny. audit records after execution. adapter exposes Aira as tools the host framework can call.

# LangChain
from aira.extras.langchain import AiraCallbackHandler
handler = AiraCallbackHandler(client=aira, agent_id="research-agent")
result = chain.invoke({"input": "Analyze Q1"}, config={"callbacks": [handler]})

# OpenAI Agents
from aira.extras.openai_agents import AiraGuardrail
guardrail = AiraGuardrail(client=aira, agent_id="assistant-agent")
search = guardrail.wrap_tool(search_tool, tool_name="web_search")

Webhook verification

Verify incoming webhook deliveries from Aira. No extra dependencies — just HMAC-SHA256 signature checking.

from aira.extras.webhooks import verify_signature

# In your webhook handler
is_valid = verify_signature(
    payload=request.body,
    signature=request.headers["X-Aira-Signature"],
    secret=your_webhook_secret,
)

pip install aira-sdk[webhooks] — no extra dependencies, the module is pure Python. This is server-to-server webhook verification, not related to the approval flow.

Content scanning

Verify agent outputs against your organization's endpoint whitelist. Configure allowed domains and content policies in the dashboard, enforce them at authorize() time.

Compliance and DORA

Aira provides built-in support for regulatory compliance:

• Compliance bundles -- sealed, Merkle-rooted evidence packets (EU AI Act Art 12, ISO 42001, SOC 2 CC7)
• DORA compliance -- ICT incident reporting, resilience testing, third-party risk management
• Public verification -- anyone can verify a receipt with verify_action(), no auth required

Self-hosted

Point the SDK at your own deployment:

aira = Aira(api_key="aira_live_xxx", base_url="https://aira.your-infra.com")

All features -- policies, receipts, settlements -- work identically on self-hosted.
