CLIProxyAPI Reverse Proxy for Antigravity: Web Search Failure in Claude Code

Users report that while using CLIProxyAPI as a reverse proxy for Antigravity to connect with Claude Code and Cherry Studio works normally, the built-in Web Search feature cannot be enabled in Claude Code, displaying a search failure message “Did 0 searches in 7s”. However, when using Antigravity directly, the search function works properly. The mapped model is gemini-claude-opus-4-5-thinking, with users suspecting it may be a configuration issue or that the API itself does not support this feature. This reveals potential functional compatibility challenges in API integration, providing valuable reference for AI tool developers and users, highlighting the need to pay attention to API configuration and functional compatibility.
