Gemini 3.5 Flash-Lite has its own web search on 3 of its 5 routes, and auto uses it when you call it on the generateContent endpoint. On every other route and endpoint Opper's engine runs the search.
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
