Lexio Python SDK

Official Python SDK for Lexio — LLM prompt management and evaluation.

Installation

pip install lexio-sdk

Quick start

from lexio import LexioClient

client = LexioClient(api_key="lx_live_...")

# Fetch a prompt
prompt = client.get_prompt("my-prompt", variables={"topic": "AI"})
print(prompt.text)

# Run tests across models
from lexio.models import RunTestsConfig, PromptEntry

result = client.run_tests(RunTestsConfig(
    prompts=[PromptEntry(slug="my-prompt")],
    models=["openai/gpt-4o-mini", "anthropic/claude-3-haiku"],
))
for r in result.results:
    print(r.model_id, r.output)

BYOK (Bring Your Own Key)

Pass your own provider API keys — they are used in-memory and never stored:

client = LexioClient(api_key="lx_live_...", byok_keys={"openai": "sk-..."})

Or register keys permanently via the Lexio dashboard (Settings → Provider Keys).

Async client

from lexio import AsyncLexioClient

async with AsyncLexioClient(api_key="lx_live_...") as client:
    result = await client.run_tests(config)

Requirements

• Python 3.11+
