+# 1Point3Acres
+
+**Mode**: 🔐 Browser · **Domain**: `1point3acres.com`
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `opencli 1point3acres hot` | Hot forum topics |
+| `opencli 1point3acres threads` | Hot thread list from the public API |
+| `opencli 1point3acres forums` | Public forum list |
+| `opencli 1point3acres posts <tid>` | Thread posts (auth required) |
+| `opencli 1point3acres search <query>` | Search threads (auth required) |
+
+## Usage Examples
+
+```bash
+# Hot topics
+opencli 1point3acres hot --limit 10
+
+# Equivalent public API thread list
+opencli 1point3acres threads --limit 10 --page 1
+
+# List forum IDs and names
+opencli 1point3acres forums
+
+# Read thread posts (requires login)
+opencli 1point3acres posts 1171864 --limit 20
+
+# Search (requires login)
+opencli 1point3acres search "USC CS"
+
+# JSON output
+opencli 1point3acres hot --limit 10 -f json
+```
+
+## Prerequisites
+
+- `hot`, `threads`, and `forums`: no browser or login required.
+- `posts` and `search`: Chrome running with the [Browser Bridge extension](/guide/browser-bridge) installed and logged into `1point3acres.com`.
+
+## Notes
+
+- Public commands use `https://api.1point3acres.com/api/forums` and `https://api.1point3acres.com/api/threads`.
+- `posts` uses `POST https://api.1point3acres.com/api/threads/<tid>/posts`.
+- `search` uses `GET https://api.1point3acres.com/api/search`.
+- The `fid` parameter on `threads` is not exposed because the upstream API currently ignores it.
