@pi-lab/xsearch

A pi extension that adds an xsearch tool powered by xAI Grok x_search.

Install

pi install npm:@pi-lab/xsearch

Usage

Set your xAI API key before starting pi:

export XAI_API_KEY=<your-api-key>
pi

You can also provide XAI_API_KEY through @pi-lab/env.

Once installed and configured, ask pi to search X/Twitter. For example:

Search X for what people are saying about the latest Grok release.

The tool returns Grok's answer plus X citation URLs. It is not a raw tweet API and does not guarantee original post objects.

Settings

Configure behavior in pi settings. User settings live at ~/.pi/agent/settings.json; project settings live at <cwd>/.pi/settings.json. Project settings override user settings.

{
  "xsearch": {
    "model": "grok-4-1-fast-non-reasoning",
    "enableImageUnderstanding": false,
    "enableVideoUnderstanding": false
  }
}

Defaults:

• model: grok-4-1-fast-non-reasoning
• enableImageUnderstanding: false
• enableVideoUnderstanding: false

See the official xAI docs when choosing a model and estimating cost:

• xAI models — available models, pricing, and tool costs.
• xAI X Search — supported x_search behavior and parameters.

For most routine searches, use a fast/non-reasoning model such as grok-4-1-fast-non-reasoning. Use a stronger reasoning model only when you need deeper synthesis, since model choice affects latency and token cost. Media understanding can add extra cost, so it defaults to disabled.
