Real-time web search with :online
:online variant is deprecated. Use the openrouter:web_search server tool instead, which gives the model control over when and how often to search.If your application already provides the web_search tool (e.g. OpenAI’s built-in web search tool type), OpenRouter automatically recognizes it and hoists it to the openrouter:web_search server tool. This means you can safely remove the :online suffix from any model slug. As long as your application exposes the web_search tool, web search still works as a server tool with any model on OpenRouter.:online variant enables real-time web search capabilities for any model on OpenRouter.
:online to any model ID:
{
"model": "openai/gpt-5.2:online"
}
web plugin, and is exactly equivalent to:
{
"model": "openrouter/auto",
"plugins": [{ "id": "web" }]
}
