Quick start

from lexprotocol import attest

# Before or after a regulated action, get a compliance attestation
result = attest("credit_decision", "My lending AI system")

print(result.citation)
# → "LexProtocol Attestation LEX-ATT-20260715-a1b2c3 | credit_decision | EU | Inhouselegal.co"

print(result.risk_tier)       # → "high_risk"
print(result.compliant)       # → True
print(result.applicable_articles)  # → ["Article 6", "Article 9", "Annex III"]

Classify risk tier

from lexprotocol import classify

tier = classify("My hiring recommendation system", use_case="employment_screening")
print(tier.risk_tier)  # → "high_risk"
print(tier.basis)      # → "Employment decisions fall under Annex III..."

For AI agent frameworks

LangChain

from lexprotocol import attest
from langchain.agents import tool

@tool
def make_credit_decision(applicant_data: str) -> str:
    """Make a credit decision with EU AI Act compliance."""
    decision = your_model.predict(applicant_data)
    attestation = attest("credit_decision", "LangChain credit scoring agent")
    return f"{decision}\n\n{attestation.citation}"

CrewAI

from lexprotocol import attest

class ComplianceAgent(Agent):
    def execute_task(self, task):
        result = super().execute_task(task)
        if task.requires_compliance:
            att = attest(task.action_type, self.role)
            result.metadata["attestation"] = att.citation
        return result

AutoGen

from lexprotocol import attest

def compliant_action(action_type, system_desc, action_fn, *args, **kwargs):
    """Wrapper that attests any agent action."""
    attestation = attest(action_type, system_desc)
    result = action_fn(*args, **kwargs)
    return {"result": result, "attestation": attestation.citation}

Configuration

import os
os.environ["LEXPROTOCOL_API"] = "https://lexprotocol.fly.dev"  # default

# Or use the client directly
from lexprotocol import LexProtocolClient
client = LexProtocolClient(api_base="https://lexprotocol.fly.dev")
result = client.attest("credit_decision", "My system")

Zero dependencies

lexprotocol uses Python's built-in urllib by default. Optionally install requests or httpx for better performance:

pip install lexprotocol[requests]
