Web search

fx can search current public information and cite its sources. The selected model decides when to use web_search.

Ask explicitly when you need current information or citations:

$fx ask "Search the web for the latest stable Zig release. Use official sources and cite them."

In the interactive shell, write the same request as a normal prompt.

How it works

fx sends the model's query to Perplexity Search through AI Gateway, then the model answers with source links. Search results are untrusted and cannot override your instructions or permissions.

Choose sources

Include the relevant country, language, date range, or preferred sources in your prompt:

Search the web for the latest stable Zig release. Prefer ziglang.org and cite the relevant pages.

Source preferences guide the search but are not strict domain filters. If you need fx to read an exact public URL, provide it and ask fx to use web_fetch.

`web_search` and `web_fetch`

Tool	Use it to
`web_search`	Find current information across the public web.
`web_fetch`	Read one known public URL.

Neither tool signs in, clicks controls, or accesses private pages.

Permissions

web_search is read-only. An allow rule enables it, while ask or deny hides it from the model. See Permissions to configure rules.
