SDK

Stratix Python SDK quickstart — install, authenticate, run an evaluation in code.

The layerlens PyPI package (v1.3.0) is the Python client SDK for Stratix. Install, set an API key, and you can do everything the Premium UI does — programmatically.

1. Install

One pip command, three minutes.

Start

2. First evaluation via SDK

Run a benchmark evaluation from Python.

Start

Why use the SDK

• Automate. CI/CD gates, scheduled trace evaluations, batch jobs.
• Integrate. Wire Stratix into your existing data pipeline.
• Share recipes. Sample programs across every major AI agent surface — copy, paste, ship.

Samples for the AI agent ecosystem

Stratix ships first-class samples for the platforms your team is most likely already on:

MCP Server

Evaluate Model Context Protocol servers and tool-use trajectories.

Browse

Claude Code Skills

Score Claude Code skill invocations, deltas, and policy gates.

Browse

Claude CoWork

Trace multi-agent CoWork sessions and compare runs.

Browse

CopilotKit

Wire CopilotKit-powered agents into Stratix traces, judges, and CI gates.

Browse

OpenAI Agents SDK

End-to-end coverage for the OpenAI Agents pattern.

Browse

LangChain / LlamaIndex / Haystack / DSPy

Framework-native instrumentation samples.

What's the SDK shape

from layerlens import Stratix

client = Stratix() # picks up LAYERLENS_STRATIX_API_KEY from env

# 11 resource handlers
client.models # public model catalog
client.benchmarks # public benchmark catalog
client.evaluations # private evaluations
client.scorers # code graders
client.judges # LLM judges
client.judge_optimizations # GEPA runs
client.traces # trace ingest + browse
client.trace_evaluations # score traces
client.results # result browsing
client.public # public-only convenience namespace
client.errors # exception types

Every method has a sync and an async form. client.evaluations.create(...) and client.evaluations.acreate(...).
