Responses Web Search

As of March 23, 2026, Crazyrouter production has verified gpt-5.5 on the Responses API using:
  • tools: [{ "type": "web_search_preview" }]
  • an output sequence of web_search_call, then message
Claude does not currently support POST /v1/responses. For Claude web search, use POST /v1/chat/completions or the native Claude path instead.

Current Verification Rule

If you need to confirm that the model actually searched the web, the safest current checks are:
  • whether web_search_call appears in output
  • whether the final answer still arrives as a message
This page no longer keeps older outdated examples, and it does not document un-revalidated search parameters as the current primary path.
