WARNING: NOT keyless — requires ZEN_API_KEY. https://opencode.ai/zen/v1 returns 401 "Missing API key" without auth. Use @chirag127/keyless-ai or another keyless provider instead.

OpenCode Zen client. OpenAI-compatible chat(). Requires ZEN_API_KEY env var — chat() throws immediately without it.

Install

npm i @chirag127/keyless-opencode-zen

Use

// ZEN_API_KEY must be set in env — chat() throws without it
process.env.ZEN_API_KEY = 'your-key';
import { chat, MODELS, DEFAULT_MODEL } from '@chirag127/keyless-opencode-zen';

const reply = await chat('Explain HMAC in one line.');
await chat([{ role: 'user', content: 'hi' }], { model: 'opencode/nemotron-3-super-free' });

API

chat(messages, opts?) => Promise<string>

Throws Error immediately if ZEN_API_KEY is not set. Otherwise POSTs {baseUrl}/chat/completions with Authorization: Bearer <ZEN_API_KEY>.
