# Node.js

> Minimal `fetch`-based client. No SDK install required.

## Setup

```bash theme={null}
export AGNTIX_API_KEY=pk_live_xxxxxxxxxxxxxxxx
```

## Tiny client

```javascript theme={null}
const BASE = "https://api.agntix.ai";

async function agntix(path, init = {}) {
  const res = await fetch(`${BASE}${path}`, {
    ...init,
    headers: {
      "x-api-key": process.env.AGNTIX_API_KEY,
      "Content-Type": "application/json",
      ...init.headers,
    },
  });
  if (!res.ok) {
    throw Object.assign(new Error(`Agntix ${res.status}`), {
      status: res.status,
      body: await res.json().catch(() => null),
    });
  }
  return res.json();
}
```

## Examples

```javascript theme={null}
const models = await agntix("/v1/chat/models");

const agent = await agntix("/v1/chat/agents", {
  method: "POST",
  body: JSON.stringify({
    name: "Support bot",
    modelId: "gpt-4o-mini",
    systemPrompt: "You are helpful.",
  }),
});

const session = await agntix("/v1/chat/chat/sessions", {
  method: "POST",
  body: JSON.stringify({ agentId: agent.id }),
});
```

## Streaming with `EventSource`

```javascript theme={null}
import { EventSource } from "eventsource";

const es = new EventSource(`${BASE}/v1/chat/events/stream`, {
  fetch: (url, init) =>
    fetch(url, {
      ...init,
      headers: { ...init.headers, "x-api-key": process.env.AGNTIX_API_KEY },
    }),
});

es.addEventListener("message.added", (e) => console.log(JSON.parse(e.data)));
```

## TypeScript

We don't ship typings yet — for now you can generate them from the OpenAPI spec:

```bash theme={null}
npx openapi-typescript https://api.agntix.ai/docs/json -o agntix.d.ts
```
