liyaengine

Official Python client for the Liya Engine public API.

Status: early access. This SDK currently covers Collections and Agents. More resources (Domains, Run, Workflows, Guardrail Policies, Evals) ship incrementally — see Roadmap.

Install

pip install liyaengine

Quickstart

from liyaengine import LiyaEngine

client = LiyaEngine(api_key="liya_...")

collection = client.collections.create(
    slug="contracts",
    label="Contracts",
    domain_keys=["legal-ops"],
)

collections = client.collections.list()

Or as a context manager (closes the underlying HTTP connection pool automatically):

with LiyaEngine(api_key="liya_...") as client:
    collections = client.collections.list()

Get an API key from your Liya Engine dashboard under Settings → API Keys.

Agents

agent = client.agents.create(
    agent_key="support-triage",
    name="Support Triage",
    goal="Triage incoming support tickets and route them to the right team.",
)

# Agents are created in draft status — deploy to activate for execution.
client.agents.deploy(agent.agent_key)

result = client.agents.run(agent.agent_key, input={"message": "My order hasn't arrived yet."})

history = client.agents.list_runs(agent.agent_key)

Error handling

Every failed request raises LiyaEngineAPIError, carrying the API's code, message, and HTTP status:

from liyaengine import LiyaEngineAPIError

try:
    client.collections.create(slug="contracts", label="Contracts", domain_keys=["legal-ops"])
except LiyaEngineAPIError as err:
    if err.code == "SLUG_CONFLICT":
        # handle the conflict
        pass
    raise

Network failures and timeouts raise LiyaEngineNetworkError instead. Requests are retried automatically on 429/5xx responses and transient network errors (2 retries by default).

Configuration

LiyaEngine(
    api_key="liya_...",
    base_url="https://api.liyaengine.ai",  # override for local/staging
    timeout_s=30.0,
    max_retries=2,
)

Roadmap

• Collections
• Agents (full CRUD, deploy, run, run/session history)
• Domains (custom domain + intent CRUD)
• Run / Run (streaming)
• Workflows
• Guardrail Policies
• Evaluations
• Async client
