Sonar is moving to the Agent API.
The Perplexity Agent API keeps grounded web search, and adds multi-step research, code execution, built-in tools, and access to multiple models through one API. On BrowseComp and WideSearch, Agent API more than doubles the best Sonar score.
Sonar endpoints are fully available today and retire on September 27, in 45 days.
See the Migration Guide for more details: Migrate from Sonar to the Agent API.
