Start the server first:

lizard-llm serve --model active

Python

from openai import OpenAI
client = OpenAI(base_url="http://127.0.0.1:8013/v1", api_key="lizard-local")
res = client.chat.completions.create(
    model="active",
    messages=[{"role": "user", "content": "Hello"}],
)
print(res.choices[0].message.content)

Node.js

import OpenAI from "openai";
const client = new OpenAI({ baseURL: "http://127.0.0.1:8013/v1", apiKey: "lizard-local" });

curl

curl http://127.0.0.1:8013/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model":"active","messages":[{"role":"user","content":"Hi"}]}'

The key is ignored — nothing leaves your computer — but most clients insist on a value, so give it anything.

Anything that reads OPENAI_BASE_URL (LangChain, LlamaIndex, lots of editor plugins) can point at Lizard the same way:

OPENAI_BASE_URL=http://127.0.0.1:8013/v1
OPENAI_API_KEY=lizard-local
