# pi-deepseek-search

![demo](https://github.com/bxff/pi-deepseek-search/raw/HEAD/demo.gif)

```bash
pi install npm:pi-deepseek-search
```

Adds web search to Pi using DeepSeek's `web_search_20260209` server side tool (previously undocumented). Only available on DeepSeek's Anthropic-compatible endpoint, so this switches your search calls there automatically. No extra API keys or config needed if you use DeepSeek in Pi.

> May 26, 2026: DeepSeek has now [officially documented](https://api-docs.deepseek.com/quick_start/agent_integrations/claude_code) the Anthropic API web search tool support.

## Limitations

Only works with DeepSeek models. The search runs on DeepSeek's servers during inference, so you can't use it with Anthropic, OpenAI, or any other provider.

Defaults to `deepseek-v4-flash`. Set `DEEPSEEK_SEARCH_MODEL` to change it.
