# NOMYO.js Documentation

Comprehensive documentation for the NOMYO secure JavaScript/TypeScript chat client — a drop-in replacement for OpenAI's `ChatCompletion` API with end-to-end encryption.

To use this library you need an active subscription on [NOMYO Inference](https://chat.nomyo.ai/).

## Quick Start

```javascript
import { SecureChatCompletion } from 'nomyo-js';

const client = new SecureChatCompletion({ apiKey: process.env.NOMYO_API_KEY });

const response = await client.create({
  model: 'Qwen/Qwen3-0.6B',
  messages: [{ role: 'user', content: 'Hello!' }],
  security_tier: 'standard',
});

console.log(response.choices[0].message.content);
```

## Key Features

- **End-to-end encryption** — AES-256-GCM + RSA-OAEP-4096. No plaintext ever leaves your process.
- **OpenAI-compatible API** — `create()` / `acreate()` accept the same parameters as the OpenAI SDK.
- **Browser + Node.js** — single package, separate entry points for each runtime.
- **Automatic key management** — keys are generated on first use and optionally persisted to disk (Node.js).
- **Automatic key rotation** — RSA keys rotate on a configurable interval (default 24 h) to limit fingerprint lifetime.
- **Security tiers** — per-request routing to `standard`, `high`, or `maximum` isolation hardware.
- **Retry with exponential backoff** — automatic retries on 429 / 5xx / network errors (configurable).
- **Resource lifecycle** — `dispose()` immediately zeros in-memory key material and stops the rotation timer.
