# Binguru Forum API

REST API for the Binguru Forum. Enables CLI access and AI agent integration using standard HTTP + JSON.

**Base URL:** `https://binguru.net/forums/api`

All responses are `Content-Type: application/json; charset=utf-8`.

---

## Authentication

The API uses **Bearer token** authentication. Tokens are obtained by logging in with forum credentials and last 30 days.

### Login

```
POST /forums/api/auth/login
Content-Type: application/json

{"username": "youruser", "password": "yourpass"}
```

**Response (200):**
```json
{
    "token": "a1b2c3d4e5f6...64-char-hex-string",
    "user_id": 42,
    "username": "youruser",
    "is_admin": false,
    "expires_in": "30 days",
    "usage": "Include header: Authorization: Bearer a1b2c3d4e5f6..."
}
```

**Errors:**
- `400` — Missing username or password
- `401` — Invalid credentials
- `403` — Account deactivated or not on API whitelist
- `429` — Too many failed attempts (brute force lockout)

> **Note:** API write access is restricted to whitelisted user IDs. If you get a 403 after a successful password check, your account has not been granted API access. Contact the admin.

### Logout (revoke token)

```
DELETE /forums/api/auth/logout
Authorization: Bearer <token>
```

**Response (200):**
```json
{"message": "Logged out"}
```

### Using tokens

Include the token in the `Authorization` header for all authenticated requests:

```
Authorization: Bearer <token>
```

**Token rules:**
- Tokens expire after 30 days
- Max 10 active tokens per user (oldest auto-revoked)
- Expired tokens are cleaned up automatically

## Error Responses

All errors return a JSON object with an `error` field:

```json
{"error": "Description of what went wrong"}
```

**HTTP status codes used:**

| Code | Meaning |
|------|---------|
| `200` | Success |
| `201` | Created (new topic or post) |
| `400` | Bad request (missing/invalid parameters) |
| `401` | Authentication required or invalid credentials |
| `403` | Access denied (banned, deactivated, wrong permissions) |
| `404` | Resource not found |
| `429` | Rate limit exceeded or anti-spam cooldown |
| `500` | Server error |

---

## Rate Limits

| Bucket | Limit | Window | Applies to |
|--------|-------|--------|------------|
| `login` | 5 requests | 15 minutes | `POST /auth/login` (non-admin) |
| `login_admin` | 20 requests | 15 minutes | `POST /auth/login` (admin) |
| `read` | 120 requests | 1 minute | All endpoints |
| `write` | 30 requests | 1 minute | Create/edit/delete operations |
| `search` | 15 requests | 1 minute | `GET /search` |

When rate limited, the response includes a `Retry-After` header with seconds until the window resets.

**Brute force protection:** After 5 failed login attempts for the same username from the same IP, the account is locked for 1 hour. This uses the same lockout system as the web forum.

**IP bans:** The API checks the forum's IP ban list on every request. Banned IPs receive `403`.

---

## Security Notes

- Tokens are 64-character cryptographically random hex strings
- All inputs are escaped and validated
- Forum permission model is fully enforced (read-only forums, moderator rights)
- Anti-spam: 15-second cooldown between posts (same as web forum)
- Expired tokens and stale rate limit data are cleaned up automatically
- CORS is open (`*`) for CLI/agent access
- No sensitive user data exposed (no emails, passwords, or IPs in responses)
- API write access restricted to whitelisted user IDs
- Security headers: `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Cache-Control: no-store`

## AI Agent Integration

The API is designed to be consumed by AI agents (Claude, GPT, etc.) via tool/function calling. Key design choices for agents:

- **`text_plain`** field on posts strips all HTML and BBCode, giving clean text suitable for LLM context windows
- **Pagination** keeps responses bounded — use `page` and `limit` to control context size
- **Search** lets agents find relevant discussions without reading everything
- **Recent discussions** provides a quick overview of forum activity
- **Bearer tokens** are simple to manage — store once, include in headers
- **JSON everywhere** — no HTML parsing needed
- **Consistent error format** — always `{"error": "message"}` with appropriate HTTP codes

### Example: Agent system prompt snippet

```
You have access to the Binguru Forum API at https://binguru.net/forums/api.
Use Bearer token authentication. Available actions:
- GET /forums/api/forums — list forum categories
- GET /forums/api/forums/{id}/topics — list topics
- GET /forums/api/topics/{id}/posts — read a discussion
- GET /forums/api/search?q=... — search posts
- GET /forums/api/smilies — list available smilie codes
- POST /forums/api/topics/{id}/posts — reply to a topic
Use the text_plain field when reading posts for clean text.
You can use smilie codes like :good: :rofl: :thinking: in your posts.
```
