# API Reference

> Hyperscape game server API endpoints and WebSocket events

## Overview

The Hyperscape server exposes both REST and WebSocket APIs for game interactions.

<Info>
  The API is primarily designed for internal use by the game client and ElizaOS agents. Direct API access requires authentication.
</Info>

## Base URL

<CodeGroup>
  ```bash Production theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
  https://api.hyperscape.lol
  ```

  ```bash Development theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
  http://localhost:5555
  ```
</CodeGroup>

## Authentication

All authenticated endpoints require a Bearer token in the Authorization header:

```bash theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
curl -H "Authorization: Bearer <your-token>" \
  https://api.hyperscape.lol/api/v1/player
```

<ResponseField name="Authorization" type="string" required>
  Bearer token obtained from Privy authentication
</ResponseField>

```bash theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
curl https://api.hyperscape.lol/health
```

<Accordion title="Response">
  ```json theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
  {
    "status": "ok",
    "timestamp": "2025-01-05T12:00:00Z",
    "version": "1.0.0"
  }
  ```
</Accordion>

### Player

</ParamField>

<ParamField path="POST /api/v1/player" type="endpoint">
  Create or update player
</ParamField>

### World State

<ParamField path="GET /api/v1/world" type="endpoint">
  Get current world state snapshot
</ParamField>

<ParamField path="GET /api/v1/world/areas" type="endpoint">
  List all world areas
</ParamField>

### Admin Endpoints

<Warning>
  Admin endpoints require the `x-admin-code` header with a valid admin code. These are for server management only.
</Warning>

<ParamField path="POST /admin/graceful-restart" type="endpoint">
  Request server restart after current duel ends (zero-downtime deployment)
</ParamField>

```bash theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
curl -X POST https://api.hyperscape.lol/admin/graceful-restart \
  -H "x-admin-code: YOUR_ADMIN_CODE"
```

<Accordion title="Response">
  ```json theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
  {
    "success": true,
    "message": "Graceful restart requested",
    "duelActive": true,
    "willRestartAfterDuel": true
  }
  ```
</Accordion>

<ParamField path="GET /admin/restart-status" type="endpoint">
  Check if graceful restart is pending
</ParamField>

```bash theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
curl https://api.hyperscape.lol/admin/restart-status \
  -H "x-admin-code: YOUR_ADMIN_CODE"
```

<Accordion title="Response">
  ```json theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
  {
    "restartPending": true,
    "duelActive": true,
    "currentPhase": "FIGHTING"
  }
  ```
</Accordion>

**Graceful Restart Behavior**:

* If no duel active: restarts immediately via SIGTERM
* If duel in progress: waits until RESOLUTION phase completes
* PM2 automatically restarts the server with new code
* Enables zero-downtime deployments for the duel arena stream

## WebSocket Events

Connect to the game server via WebSocket for real-time updates:

```javascript theme={"theme":{"light":"github-light","dark":"tokyo-night"}}
const ws = new WebSocket('wss://api.hyperscape.lol/ws');

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log('Received:', data);
};
```
