client = OpenAI(
    base_url="https://evrona.ru/v1",
    api_key="ev-YOUR_KEY",
)

completion = client.chat.completions.create(
    model="z-ai/glm-5.3-flash",
    messages=[
        {
            "role": "user",

Claude Code and Anthropic-protocol clients

Clients that speak the Anthropic protocol take the address without /v1: ANTHROPIC_BASE_URL=https://evrona.ru. The model ID stays the same.

macOS / Linux

export ANTHROPIC_BASE_URL=https://evrona.ru
export ANTHROPIC_AUTH_TOKEN=ev-YOUR_KEY
export ANTHROPIC_MODEL=z-ai/glm-5.3-flash
