xAI web search

by xAIWeb search

xAI web search lets Grok search and browse the web in real time and answer with citations, held to or kept off up to five domains per request. xAI also has a separate X search tool for posts, users and threads on X. On Opper, opper:web_search on auto uses it on the routes that have it, and Opper's own engine everywhere else. Pin "engine": "native" to require it, or pin Jina or SearchBase to keep searches in the EU instead. It runs on 20 routes in the catalogue today.
