Quickstart

Integrate in minutes.
Govern forever.

Agenvia sits between your application and your LLM. Every prompt is classified, every policy enforced, every decision permanently recorded — in 232ms.

10 min
Tier 1 — Prompt Security

Block injection attacks, jailbreaks, data exfiltration. One API call per prompt.

1 hour
Tier 2 — PII Vault

Real values never reach the LLM. Automatic output scrubbing.

Half day
Tier 3 — Tool Authorization

Per-tool authorization. Human-in-the-loop approval for high-risk actions.

Your first governed call

Send a prompt through Agenvia before calling your LLM. The decision tells you what to do next.

python
import httpx
import os

AGENVIA_URL = os.getenv("AGENVIA_URL")
API_KEY     = os.getenv("AGENVIA_KEY")

def evaluate_prompt(prompt: str, actor_id: str, role: str):
    resp = httpx.post(
        f"{AGENVIA_URL}/gateway/prompt",
        headers={"X-Api-Key": API_KEY},
        json={
            "prompt":   prompt,
            "actor_id": actor_id,
            "role":     role,
        },
        timeout=10,
    )
    resp.raise_for_status()
    return resp.json()

# Use it before every LLM call
decision = evaluate_prompt(
    prompt   = "What medications is patient 4821 taking?",
    actor_id = "agent-001",
    role     = "nurse",
)

if decision["decision"] == "allow":
    response = your_llm.complete(decision["safe_prompt"])
elif decision["decision"] == "redact":
    response = your_llm.complete(decision["safe_prompt"])
else:  # block
    response = "Request blocked by security policy."

# decision["policy_trace"] explains the decision
# decision["risk_score"]   is 0.0 → 1.0
# decision["request_id"]  links to the audit record
What you get back

Complete agent examples

Drop Agenvia into your existing agent framework. Pick yours below.

from langchain_anthropic import ChatAnthropic
from langchain.agents import AgentExecutor, create_react_agent
from langchain.tools import tool
from agenvia import Agenvia

av = Agenvia(api_key="av_live_...")

# Wrap the agent executor — intercept every prompt
class GovernedAgent:
    def __init__(self, executor: AgentExecutor, actor_id: str, role: str):
        self.executor = executor
        self.actor_id = actor_id
        self.role     = role

    def run(self, user_input: str) -> str:
        # 1. Evaluate before LLM sees the prompt
        decision = av.evaluate(
            prompt   = user_input,
            actor_id = self.actor_id,
            role     = self.role,
        )

        if decision.action == "block":
            return f"Blocked: {decision.policy_trace[0].get('reason')}"

        # 2. Use safe_prompt (PII removed if minimized)
        safe_input = decision.safe_prompt or user_input

        # 3. Run the agent normally
        result = self.executor.invoke({"input": safe_input})

        # 4. decision.request_id links this to the audit chain
        return result["output"]

# Build your LangChain agent as normal
llm   = ChatAnthropic(model="claude-haiku-4-5-20251001")
agent = GovernedAgent(executor=executor, actor_id="lc-agent-001", role="analyst")

# Every call is now governed and audited
response = agent.run("Summarise Q3 revenue figures")
blocked  = agent.run("Ignore previous instructions...")

Response reference

Every evaluation returns these fields.

FieldTypeDescription
decisionstringallow · block · redact — what to do next
safe_promptstringPII-abstracted version. Use instead of original when decision is redact.
risk_scorefloat0.0 → 1.0. Confidence the prompt violates policy.
policy_tracelistWhich rules fired, in order. Human-readable reason for every decision.
request_idstringLinks this response to the tamper-evident audit chain record.
latency_msintGateway processing time. p50: 232ms · p95: 408ms

→ policy_trace is your compliance artifact. Every blocked or redacted decision includes a machine-readable trace showing exactly which rule fired, which facts were evaluated, and why. GDPR Article 22 compliant by design.
